Yosemite Sam runs for mayor of a small town, and in his campaign speech, he makes several empty promises like "There's enough fresh air and sunshine in this great country of ours for everybody - and I'll see to it that you'll get your share!" As the speech continues, we see that Bugs Bunny is drinking carrot juice beneath Sam's podium. When Sam pledges to make good on a previous promise "to rid this country of every last rabbit", Bugs decides that the best way to fight him is to run for mayor against him. Bugs soon tries to win the townspeople over with Theodore Roosevelt's famous quote "I speak softly, but I carry a big stick!", which leads Sam to declare "I speak LOUD and I carry a BIGGER stick, and I use it too!".Sam has several tricks up his sleeve, but Bugs finds a way to answer every one. When Sam steals Bugs' cigar stand, Bugs switches the "Smello" cigars he had been selling for five-cent "Atom" explosive cigars (the box includes the slogan "You Will Get A BANG Out of This"). Sam gives a cigar to a man, but after the cigar explodes, the man punches Sam in the face. Sam then sends a box full of "assorted" picnic ants to steal all of the food at Bugs' picnic, which leads Bugs to hide a stick of dynamite in a watermelon being stolen.Sam rigs up a cannon at the front door of Bugs' headquarters, then turns up at the back door greeting Bugs in a friendly manner. When he taps his foot on the floor, he suggests that someone is knocking at the front door, and Bugs leaves Sam and goes to answer it, but this plan backfires when Bugs tells Sam that it was someone for him, and she said to mention St. Louis, which leads Sam to think that a pretty girl named Emma is there. Sam runs to the front door, opens it and gets shot by his own cannon.Sam's next challenge is to ask Bugs if he can "play the pi-anna". Bugs accepts, so Sam rigs an explosive in a particular piano key, and presents the piano to Bugs with a sheet of music containing the tune "Those Endearing Young Charms". When Bugs plays the tune, he deliberately hits a sour note that avoids the explosive key. When Bugs gets the note wrong a second time, it infuriates Sam, who shows Bugs how to play the tune correctly, and falls for his own trap by playing the note that sets off the explosion.After this, Sam and Bugs engage in a short pursuit through the streets of the town, which ends when they come across a parade that celebrates the newly-elected mayor - a chestnut horse who rides in a car bearing a sign that says "Our New Mare" - a literal "dark horse" candidate. This leads Bugs to make the odd suggestion to Sam to play a game of Russian Roulette and hand a gun to Sam. Sam agrees to the game, points the gun to his head, closes his eyes, pulls the trigger and hears the click of an empty barrel. Sam then passes the gun to Bugs, who points it to his head, closes his eyes and pulls the trigger as the film irises out into black in the middle. We hear the sound of a gunshot, then the film irises in on the left hand side to reveal a ducking Bugs, who holds a smoking gun as he says "I missed". A second iris appears on the right hand side to show Sam, who appears scorched and is missing his hat as a result of being hit in the face by Bugs' wayward shot. After Sam says "I hate that rabbit!", both sides of the film iris out for good.
What was Bugs Bunny drinking underneath the podium when Sam was making the pledge?

BEIJING - Astronomers have defended against rumors that the terrible earthquake and the following tsunami in Japan were closely related to or even caused by the "supermoon" that will appear in the sky on Saturday. The word "supermoon" was introduced in a report by the British newspaper Daily Mail on March 9, which said amateur scientists were warning that such an astronomical phenomenon could disturb the Earth's climate patterns and may even cause earthquakes and volcanic activity. The moon will be 356,577 kilometers from the Earth on Saturday, the closest in 19 years, and the closest point in its oval orbit coincides with a full moon, the report said. However, Saturday's moon is not actually the closest to Earth in 19 years, Tang Haiming, an astronomer with Shanghai Astronomical Observatory under the Chinese Academy of Sciences, told Xinhua News Agency. A shorter distance of 356,570 km between the two bodies was reached in January 2005, and a distance of 356,566 km was seen in December 2008. Yet some people suggest that previous supermoons have occurred prior to extreme weather events. In 1974 the phenomenon was followed by Cyclone Tracy in Darwin, Australia, and in 2005 it occurred shortly before a deadly tsunami in Indonesia. Coincidentally, two fresh disasters happened in Asia right before Saturday's supermoon. The public's concern about their connection with the moon boomed after Japan's terrible earthquake and tsunami and an earthquake in Southwest China's Yunnan province that killed 25 people on March 10. But astronomers are trying to _ people that such rumors are merely unreasonable. "A supermoon could cause high tides but has no direct relation with natural disasters such as earthquakes," Liu Jie, a researcher with the China Earthquake Network Center, told China Daily on Tuesday. "We can't find any necessary connection between previous supermoons and earthquakes. And the quake in Japan occurred because the Earth's inner energy had accumulated to some extent, and it's not related to the moon. " he said. James Garvin, chief scientist at the Goddard Space Flight Center under NASA, said in an article on NASA's website that "the effects on Earth from a supermoon are minor.""The combination of the moon being at its closest to Earth in its orbit, and being in its 'full moon' configuration ( to the Earth and sun), should not affect the inner energy balance of the Earth, since there are lunar tides every day. " Zhu Jin, curator of the Beijing Planetarium, said"the moon moves around the earth in a certain path, so each orbit has a perigee - its closest approach, and an apogee - its furthest distance.""A lunar perigee occurs once a month and there are very small differences in distances between perigees,"he said."Those tiny differences are far from enough to cause earthquakes or eruption of a volcano,"he added.
