I'm not sure. Maybe it had something to do with Winters being mischievous. People like that quality. Maybe that's why mischievous people make good joke tellers. They make you aware of the absurdity of the fact that you just dropped something important to listen to something that's going to be incredibly stupid.
I don't remember many jokes, and I'm not really good at telling them. What I do remember is the way they were told. I love the way joke tellers look both ways then grab your arm and lean in furtively. I love the whole ritual that's associated with joke telling. Mischievous people are experts at creating the atmosphere that precedes a joke.
