Ok, seriously I am the lamest person alive. I cannot think of one joke. In my defense, I teach preschool and all I hear are lame knock, knock jokes that 4 year old kids make up! They go something like this:
them: knock, knock
me: who's there?
me: chicken who
them: chicken noodle soup (insert hysterical laughter from small children here)
Oh well, they keep life interesting! If you have any good jokes, but sure to leave them in the comment section!
