A neatly dressed salesman stopped a man in the street and asked, "Sir, would you like to buy a bottle of this mouthwash for $200?"

"Are you nuts?" the man screamed, aghast. "That's robbery! Of course not!"

The salesman seemed hurt, but then tried again. "Sir, since you are a bit irate," he announced, "I'll sell it to you for HALF the price, at $100!"

"You must be crazy, pal," the man replied bluntly. "Now leave me alone."

The salesman reached into his briefcase and pulled out two brownies on a napkin. He told the irritated guy, "Sir, I'd like to apologize for annoying you. In return, I'll share one of my brownies with you."

The man took the brownie and took the bite. Suddenly, he gagged and spat it out. "Hey," he snarled, "This brownie tastes like crap!!"

"It is," replied the salesman, with a grin. "Wanna buy some mouthwash?"
