Yo Mamma so stupid she put on bug spray before she goes to the flee market!
A parrot was in a pet shop with a string attached to each leg when a man walked in looking to buy a pet. A shopkeeper came over and started to try and sell him a dog when the man noticed the parrot. He asked what the strings were for and the shopkeeper replied, "Well, if you pull the right string the parrot says, 'Polly wanna cracker'. If you pull the left string it says, 'my name's Sam'". The man being of the inquisitive nature tried both and thought it was really neat, but was still curious. So he asked what would happen if he pulled both strings, the parrot piped up, "I'd fall off the perch you idiot!"
Yo' Mama's cooking is so bad, the homeless give it back.
A stranger was seated next to Little Johnny on the plane when the stranger turned to the Little Johnny and said, "Let's talk. I've heard that flights will go quicker if you strike up a conversation with your fellow passenger." Little Johnny, who had just opened his book, closed it slowly, and said to the stranger, "What would you like to discuss?" "Oh, I don't know," said the stranger. "How about nuclear power?" "OK," said Little Johnny. "That could be an interesting topic.But let me ask you a question first." "A horse, a cow, and a deer all eat grass. The same stuff. Yet a deer excretes little pellets, while a cow turns out a flat patty, and a horse produces clumps of dried grass. Why do you suppose that is?" "Jeez," said the stranger. "I have no idea." "Well, then," said Little Johnny, "How is it that you feel qualified to discuss nuclear power when you don't know shit?"
