When I was considerably younger than I am now, I used to tell jokes (There are no jokes to be told now. Alas, I have lived too many years and life has sucked all my smiles from the world...) My jokes were usually incredibly simple. They all had a common theme...
A KNIFE.
Yep. I used to tell jokes about people who had knives. For example, Timmy was walking home from school, and he pulled out a knife! (At this point, I believed that everyone should be laughing as hard as they are ever going to laugh.)
