What cold jokes have you heard that are worth sharing?

I have heard a big joke since I was a child. It is cold and not funny, so I want to tell it now. Once upon a time, a ghost farted and died. I've been telling this joke since primary school, and it doesn't work, and what he said won't make people laugh. I'm just a bit addicted to talking sometimes, such as thinking about others in Doby, or popping up when I'm bored. Less times, and then speak fast. I think this is another way of saying it.
