Haha I like that one Sephiroth's Cage! Okay here's one:

A blond woman decides she wants to buy a new microwave. So she goes to the store to go buy one. When she gets there she says to the clerk "I want to buy that microwave, how much is it?" The clerk says, "I'm not selling this microwave to you because you're blond." She is outraged but still wants to buy it. So she goes home and dyes her hair. Then she goes to the same store the next day. The same clerk says "No, I'm still not selling you the microwave." So she goes home and changes her outfit then comes back to the same store the next day. The clerk still says, "No, ma'am I told you before that you can't buy the microwave." The woman is finally disgusted and replies, "Why won't you sell me the microwave?!" The clerk responds, "Because it's a TV."
