A blonde walks into an electronics store and points to something behind the clerk. "How much is that television set?" she asks. "Sorry, we don't sell to blondes," the clerk said. So, the girl walks out. The next day, she returns wearing a brown wig. She again approaches the clerk and asks "How much is that television set behind you?" The clerk replies, "Sorry, we don't sell to blondes." Again, the girl walks out. She again tries the next day, this time wearing a red wig. She goes up to the clerk and asks "How much is that television set behind you?" The clerk again replies, "We don't sell to blondes!" Well, the girl was kind of suspicious. She asks carefully, "How do you know I'm a blond?" The clerk looks at the girl and says... "Because that's not a television, it's a microwave!"
