famous koan turned into a dumb joke This is my favorite joke to pull on someone... Ok to keep things Anon lets just say my name is Kevin... I ask the person what is the sound of one Kevin clapping... Assuming they are not Kevin and start clapping tell them they are not Kevin and so that is not the sound of one Kevin clapping continue to step peanut butter.... If they happen to be named Kevin.. Run away. Step peanut butter... If they say I don't know what is the sound of one Kevin clapping.. Clap 3 times and start chuckling to yourself.
