A farmer's donkey dies. His son gets an idea on how to make some money.

Sometime later he turns up at dinner with $200. "Where did you get that money?" His father asks.

"I sold raffle tickets for the donkey" his son replied.

"What?!?" Shouts his father. "You can't sell raffle tickets for a donkey that you know has already died! Weren't people mad?"

"Just the guy who won" said the son, "so I gave him his money back."
