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

Aghast, the man said, "Are you NUTS!, that's robbery!"

The salesman seemed hurt and then tries again, "Sir, since you are a bit irate, I'll sell it to you for 1/2 price at $100."

Again, the man replies bluntly, "you must be crazy pal, now go away!"

The salesman then reaches into his briefcase and pulls out 2 brownies and begins munching away on one of them.

He tells the irate guy,"Sir, please share one of my brownies since I have annoyed you so much".

Unwrapping the brownie, the guy takes a bite, suddenly the guys spits it out and says,"HEY" he snarled, "this brownie tastes like crap!!!

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