Dad & Dave saw an ad in the daily newspaper and bought a mule for $100.
The farmer agreed to deliver the mule the next day.
The next morning the farmer drove up and said, "Sorry, fellows, I have some bad news, the mule died last night."
Dad & Dave replied, "Well, then just give us our money back."
The farmer said, "Can't do that. I went and spent it already."
They said, "OK then just bring us the dead mule."
The farmer asked, "What in the world ya'll gonna do with a dead mule?"
Dad said, "We're gonna raffle him off."
The farmer said, "You can't raffle off a dead mule!"
Dad said, "We shore can! Heck, we don't hafta tell nobody he's dead!"
A couple of weeks later, the farmer ran into Dad & Dave at the local grocery store and asked, "What'd you fellers ever do with that dead mule?"
They said, "We raffled him off like we said we wuz gonna do."
Dad said, "Hell, we sold 500 tickets fer two dollars apiece and made a profit of $898."
The farmer said, "My Lord, didn't anyone complain?"
Dave said, "Well, the feller who won got upset. So we gave him his two dollars back."
Dad & Dave now work for the Gillard government. They're financial advisers to Wayne Swan, Australia's finance minister.
