I think my favourite bad joke of all time was from my friends little sister a long time ago. I think she was only like 4-5 or something. She came up all "Why did the chicken cross the road?" and when we said we did not know and asked her to inform us she screamed "A BRICK!!!" and ran away cackling like a witch. It made no sense and it was awesome
