Candidate passages:
One day, the family goes to a supermarket.
At the checkout, Brother and Sister see their favorite candies and make a fuss until Papa gives in to their behavior and buys them.
On the way out to the parking lot, Brother and Sister spot a Bucking Frog similar to the Bucking Duck they ride at the mall.
They begin to whine and beg, even worse than they did inside, and Papa gives in once again and buys them a ride.
En route to the car, the cubs spot a stand that sells toy cats that squeak.
They have their worst screams yet, and Papa, embarrassed, reluctantly gives in to their demand and buys each of them a cat.
When they get home, Papa and Mama are upset at the cubs' behavior and have a talk with them about how greedy cubs that want everything can never be satisfied.
Gramps and Gran come to visit, and Brother and Sister greet them by jumping up and down and yelling, demanding gifts.
Infuriated (as this is the last straw in his opinion), Papa sends the cubs to their rooms.
Papa explains to Gramps and Gran that Brother and Sister have the worst case of the gimmies, and Gramps states that Papa had the gimmies once when he was a cub.
Gramps and Gran state that they had a deal in which when it came time for a trip to the general store, Papa could pick out a treat, a book, or a toy before they ever left the house, and that was it for the day.
If he came down with the gimmies and began whining for anything else, they would go right home and Papa would get nothing.
Papa and Mama realize that is a good idea, as do Brother and Sister.
They go to the supermarket a few days later, and Brother and Sister get the treats they decided on at the house (Brother gets a book on dinosaurs and Sister gets a box of crayons).
The plan works, much to Mama and Papa's relief (and Brother and Sister are very proud of themselves, too).
However, as they leave, the family spots a cub who also has the gimmies in the checkout.
Brother and Sister express disgust with the cub's behavior, and they leave the supermarket happily. 
In this tale, Brother, Sister, Mama, and Papa join Gramps and Gran on a picnic.
When trying to decide where to set it up however they all show disrespect.
When Papa suggests hosting it in a site he and his friends did when they were cubs, Brother's opinion is '"That was so 100 years ago...let's go somewhere better."'
When Mama suggests a creek, Sister's opinion is '"It is so dirty, worn down and full of mosquitoes...let's go somewhere better."'
Even Mama and Papa begin to disrespect Gramps and Gran causing Gramps to host a family meeting.
After discussing it everybody apologizes to one another and ultimately decide to picnic in Gramps and Gran's house. 
In Cook Islands mythology of the southern Cook Islands group, the earth goddess Papa was created when Varima-te-takere, the primordial mother goddess, plucked her out from the left side of her body.
Papa married her brother, the sky god Vatea.

Mullavey was married to actress Meredith MacRae from 1969 until 1987, when they divorced; they had one child, daughter Allison Mullavey.
He has lived with actor/writer Ariana Johns since 1999. 
Johns was born in Plymouth, but nothing is known of him until he was training as a printer and publisher for the father of the history painter Benjamin Haydon who shared the same name as his son.
Johns' landscape painting skills were encouraged by his friendship with Haydon, Turner and later local artist Charles Eastlake.
Johns became a member of the Plymouth Society of Artists and Amateurs and would invite artists to stay.
Turner stayed with him during the summer of 1813.
Turner and Johns went on sketching trips together.
In 1807 Johns described his profession as bookseller when he successfully applied for a patent which covered the manufacture and composition of an external paint for houses.
Regretfully Johns pictures can be frequently recognised by their dark colour as he is said to have used too much asphaltum.
which was not lightfast.
Johns and Turner's styles were similar and Johns made a painting box by hand for his sketching partner.
There are examples in John's sketchbooks of studies he made based on Turner's work.
This friendship was damaged when a painting by Johns, that was owned by the influential art critic Samuel Carter Hall, was engraved and published and erroneously attributed to Turner.
The publishers did print a correction and apology in the newspapers but this still did not prevent the same painting being sold at Christies still with an incorrect attribution to Turner.
Johns exhibited at prestigious exhibitions in London including the Royal Academy.
Despite this exposure his work was later confused with Turner's on two other occasions.
Turner is said to have "tired of Johns' copying" although they were still acquaintances in 1840.
Johns and his wife Rebecca had five children at their home of North Hill Cottage in Plymouth.
The house was a centre for local artistic culture and was visited by aspiring local artists like Haydon and Samuel Prout.
Johns worked as a drawing master and he organised local exhibitions and founded a local sketching society.
Johns continued to experiment with paint and he was awarded another patent for an undercoat used to prepare materials for additional treatment in 1839.
The youngest of Johns children, John Johns is presumed to have been sent to Edinburgh University because he was a Presbyterian.
He went on to be a Unitarian minister and a notable missionary.
Johns died in Plymouth.
He has a number of paintings in national ownership and several at Plymouth City Museum and Art Gallery.
An exhibition of his work was held in Australia in 1979 and a recent sale of a sketchbook raised €22,844.
