Sam was sitting in the living room laughing hysterically at presumably nothing. (He does this frequently – He has something going through his mind that he finds hilarious)
Sam then came to me and said: Do you know what is really funny?
Sam: A beaver with a chainsaw.
Me: What would a beaver do with a chainsaw.
Sam: Chop down random trees and people and a squirrel.
Me: Why would he chop down people and a squirrel.
Sam: Because beavers don’t know how to use chainsaws. (Then he walked off laughing)
