Next come the knock knock jokes

Who would have thought that this could be so hilarious?.....

"Guess what?" "What?" "Chicken butt!"

"Guess who?" "Who?" "Chicken poo!"

"Guess when?" "When?" Chicken hen!"

"Guess how?" "How?" "Chicken cow!"

"Guess why?" "Why?" "Chicken thigh!"

"Guess where?" "Where?" "Chicken hair!"

Three/almost 4 year olds are easily amused.
