A man with a dog walks into a bar.

He walks over to his seat and says, "I can bet $100 to each of you that my dog can talk!"

Everybody agrees to the bet. The guy says, "Spot, speak!" The dog is silent.

"Spot, speak," the guy repeats. The dog still doesn't react. Fuming, the guy begrudgingly pays each of the bettors the agreed upon sum and leaves the bar. Outside, the guy says to the dog,

"You set me up, you stupid mutt! Do you even know how much cash I lost because of you?"

"Nonsense," says his dog. "Just imagine how much money we'll raise tomorrow from these suckers!"
