The Loony Bin

What follows is a recent conversation that really took place between two friends of mine.

Ann speaking to Dave : You know, your teeth are looking pretty white. Have you been bleaching?
Dave: Well, no. I’ve been brushing with Ajax.
Ann: WHAT??
Dave: Well, I heard that that makes them whiter. It works on bathrooms.
Ann: Well yeah. But your mouth isn’t exactly a toilet. Who told you to do that?
Dave: Wes.
Ann: You took advice from a CRACKHEAD???
