The neatly dressed salesman stopped a man in the street and asked, “Sir, would you like to buy a toothbrush for ten dollars?”

The salesman seemed hurt. “Well, then, how about a homemade brownie for five cents?”
This seemed fair, and the man handed a nickel to the salesman. Unwrapping the brownie, he took a bite; suddenly, the man spit out the mouthful.
“Say,” he snarled, “this brownie tastes horrible!”
“It is,” replied the salesman. “Wanna buy a toothbrush?”
