A man from the city is out plowing his field and gets his tractor stuck in the wet ground. A farmer driving by stops his truck and walks to the fence to call over the city feller; "You need a mule to plow such wet ground" he says.

"Where can I buy one?", asked the man from the city.
"Well, I just happened to have one for $100" says the farmer.
"I'll take him," says the other man as he counts out the money.
"I can't bring him over today. I don't work on Sunday, tomorrow OK?"
"Sure."

The next day the truck pulls up and the old farmer gets out. He says, "Sorry, bad news. I went out after breakfeast and the mule was dead."

The city feller says "Just give me my money back then."
"Can't, spent it already!"
"Well... unload the mule then."
"What ya gonna do with him?"
"Raffle him off!"
"Naw, ya cant raffle off a dead mule!"
"Just watch me! City fellers know a few tricks." He gives the farmer a wink.

One month goes by and the city man and farmer run into each other at the barber shop. "What did ya do with that dead mule?"
"Raffled him off, sold 100 tickets at $2 each and made $98 profit."
"Didn't anyone complain?"
"Just one guy so I gave him his two dollars back!"
