A blonde walks into a department store and asks the clerk if she can buy a TV as she points toward the one she wants. The clerk replies that they don't sell those TVs to blondes. Fumed, the blonde stomps out of the store and dies her hair red. She goes back to the store and asks the clerk again and again is told the same thing. The blonde leaves again and dies her hair brown. Again the store clerk tells her that they don't sell those TVs to blondes. Hysterically, the blonde asks the clerk how he could tell that she is a blonde even with the hair color change. The clerk replies," Ma'm, that's a microwave."
