Yaksgiving is a holiday celebrated by the people of Ustinkistan. When Timmy Turner's grandparents, Grandma Gladys and Grandpa Vlad, come to visit him they celebrate this holiday with his family over a six day period. It is a parody of the animal, Yak and the regular Thanksgiving.
Yaksgiving lasts for six days, much to the burden of Timmy Turner who was tormented and starved the entire duration of it. A Yaksgiving carol exists detailing the traditions to the tune of "The 12 Days of Christmas".
On the first day of Yaksgiving, we make Yaksgiving Soup!
On the second day of Yaksgiving, we shave Yaksgiving backs!
Timmy walks in on Vlad shaving Gladys' very hairy back in the bathroom. He screams and runs out. Vlad and Gladys don't seem to be enjoying it themselves.
On the third day of Yaksgiving, we drop Yaksgiving yak!
Timmy walks out of his house, when a yak drops from the sky and crushes him.
On the fourth day of Yaksgiving, we drop another yak!
Timmy quickly runs back inside of his house. He stops for a moment at the door frame, breathing a sigh of relief when he thinks he's safe, and then is crushed by another falling Yak as soon as he walks into his house.
On the fifth day of Yaksgiving, we had a yak attack!
Timmy: Wait, did the choir just say, "yak attack"?
A huge herd of Yaks rushes into Timmy's kitchen, stampeding over him.
On the sixth day of Yaksgiving, we had Yaksgiving feast!
Timmy, who apparently hasn't eaten anything in the past six days, cannot wait to finally have Yaksgiving feast. That is until Grandpa Vlad reveals what they were having: salad with thorny twigs and mayonnaise, pipping hot goat-meal, pickled weasel feet, and the main course stick bugs on a stick made of stick bugs. Timmy picks up on of the stick bugs and he is swarmed by tons of tiny smaller bugs. He then ends up on his grandparent's pet goat which runs out of the house with Timmy on its back while his grandparents chase after it with bloodhounds.
