There is a blonde and she walks into an electronic store and is looking at a tv and says to the worker "I want to but that tv over there." However the man say's "I'm sorry we don't sell to blondes.

So the blonde walks out and dyes her hair brown. The next day she goes back to the store and says "I would like to buy that tv" but the man says "I'm sorry we don't sell to blondes." So the blonde goes home and changes her clothes and shaves her head. Then goes back to the store. She says "I would like to buy that tv" but once again the man says "sorry we don't sell to blondes" the blonde screams at him "how in the hell do you know I'm a blonde?" "Because ma'am that is not a tv, it's a microwave.
