"Series Ten, Episode Seven"In an argument with the producers of "Top Gear", the presenters claimed British Leyland did produce some good cars after all.
So, they were given a budget of £1,200 (of their own money) to buy a British Leyland car in which they would face a series of challenges, for which, instead of points, they would earn money back.
Clarkson got a 1981 Rover SD1, Hammond bought a 1972 Dolomite Sprint, whereas May acquired a 1978 Princess.
Challenges included a variety of tests at the MIRA proving ground, and seeing how far the cars could be driven while full of water.
The boys also reproduced the intro of "Money" from the various squeaks and clunks their cars made.
After all the challenges, Clarkson summed up the points and declared May the winner of the challenge, as not only did he get back all that he had paid, he made a £20 profit.
Winner: May 
The story begins with Scrooge McDuck swimming in his money bin, speaking his now-famous line, "I love to dive around in it like a porpoise, and burrow through it like a gopher, and toss it up and let it hit me on the head!"
He is watched by his nephew Donald, and they discuss the relative merits of having so much money.
While looking through the window, Scrooge is alarmed to see that the Beagle Boys have bought the lot next to the money bin.
Scrooge understands that they plan to build a house on it so they can secretly drain Scrooge's money out of the bin.
Scrooge immediately faints.
Huey, Dewey and Louie ask Scrooge why he is so attached to his money, and he explains that to him it is not just money: his fortune is the result of a long life of hard work and canny action.
Every coin is a memento of an adventure.
"You'd love your money as much as I would if you'd gotten it the way I did – by thinking a little faster than the next guy, by jumping a little quicker."
Scrooge also repeats another of his now-famous mantras: he made his fortune by being "smarter than the smarties and tougher than the toughies, and I made it "square"!
"After calming down, Scrooge forms a plan: with his nephews' help, he installs a chute that allows him to empty the bin slowly, using the trucks with which the beagle boys take away the dirt of their excavations.
The money is then dumped into the bottom of a lake, owned by Scrooge.
By the time the Beagle Boys enter the bin, it is completely empty.
However, Scrooge is not at peace.
Worrying that the mud at the bottom of the lake will ruin the banknotes, he has the money brought up loads at a time and the banknotes placed in glass jars before being re-sunk.
Still with his money on the bottom of the lake Scrooge begins to miss his daily swim in his coins.
To make up for it, he decides to create a temporary money island.
But once he is indulged in swimming around in his money, one of the Beagle Boys coincidentally observes him from afar.
Realizing that the Beagle Boys have found out his where he hid his money, Scrooge immediately calls his nephews to help him guard the lake.
The Beagle Boys buy the land in the valley downstream from the lake, showing that their plan is to destroy the dam at the end, causing the water and the money to flow down onto their property.
Scrooge and his nephews defend against the Beagle Boys' varied assaults on the dam: first, they use a giant magnifying glass suspended from a weather balloon to focus sunlight on the dam, hoping to burn it.
Donald shatters the glass with a shot from an old-fashioned cannon.
Next, they force a bomb down the gullet of a fish and send it swimming toward the dam.
Luckily, Dewey is fishing, and manages to pull out the bomb and throw it away before it explodes.
Scrooge tells him to chase all the other fish downstream and then string a net across.
Third, the Beagle Boys use trained cormorants who first steal beakfuls of change from the lake, then carry napalm bombs toward the dam.
Scrooge, who learned cormorant language while trading pearls in Asia, orders the cormorants to turn around and drop their bombs on the Beagle Boys.
Fourth, the Beagle Boys seed the clouds, causing a thunderstorm, hoping a lightning bolt will be drawn to the metal in the lake, and set the dam ablaze.
Scrooge installs a large lightning rod atop the dam, wired to a cannon ball shot into the Beagle Boys' backyard.
The Beagle Boys turn to Plan Five: breeding super-termites.
One of them tricks Scrooge into buying them, thinking they are a termite-"eating" insects, and they chew through the dam.
They are unable to repair the dam quickly enough, and it breaks, sending all the money flowing down onto the Beagle Boys' land.
Scrooge, to his nephews' surprise, decides to admit defeat, and invites them to come along while he congratulates the winners.
The Beagle Boys crow over him, and as he gazes nostalgically at his money, he confesses that what he will miss most is swimming around in it.
The Beagle Boys are intrigued, more so when Scrooge demonstrates.
They decide to take a dive in themselves – and end up bashing their heads on the hard, unyielding surface of the money.
They will be unconscious for months, more than enough time for Scrooge to transport the money back onto his land.
When his nephews ask how he can dive through the money while the Beagle Boys couldn't, he admits, "it's a trick.
"Scrooge pays his nephews their wages, and as they leave, Donald remarks that Scrooge's money is nothing but trouble, for all the work it takes to guard and preserve.
Scrooge dismisses this advice, declaring "No man is poor who can do what he likes to do once in a while!"
He then goes back to gleefully swimming through his money.

Wetch kept at the for a number of years.
Joe Saad would back him with thousands of dollars, sometimes accompanying him on his trips, and sometimes not.
Wetch was soon playing matches for huge stakes; Up to $10,000 bet on a single .
In addition to Saad, Wetch was fostered by others such as veteran road player Jack Cooney, a hustler who often went under the assumed name George Carlson and was twenty years Wetch's senior.
"He taught me how to survive out there, to be patient for decent games and to manage my money right."
However, Wetch's love for gambling and for pool did not translate into a love of the hustle.
He did it because it was the only way he knew how to make money doing what he loved, but he never liked "the , the moving, the mismatches, the phony names.
""I never felt good about the hustling.
No matter how much money I made at it, I knew I didn't want to keep doing it.
Frankly, when no one knows how you play, it's like putting a gun to someone's head.
It wasn't a matter of whether you were going to win, but how much you were going to win, Early on, you make money everywhere you go.
Then it all disappears.
"  – Wetch, in "Billiards Digest" (1999)The event that finally took him off the road came in Houston in 1993.
He had made a large score playing high-stakes pool one night.
The following morning while attempting to leave his hotel room with his then girlfriend, two men shoved the two back into the room and at gunpoint demanded the money he had won.
Not satisfied with the amount of money Wetch handed over, they placed a bag over his head and beat him.
Though he escaped the ordeal with only minor injuries, he promised himself he would only make one more road trip to gather a stake, and then he would quit.
He made that final trip and used the money to open up a pool room with partner David Wagner, Jimmy's Pro Billiards in Columbia Heights, Minnesota.
The following year, in 1994, he took the ultimate step for a road player, shucking aside his anonymity by going pro.
