99 Problems

Listen up, chucklehead! This joke is based on a real song by Jay Z. The joke sets up a scenario where Jay Z is getting pulled over by the cops and then uses a line from his song to answer the question. So, instead of listing problems, he cleverly uses his song lyric to imply that a "bitch" is not one of them. It's funny because it's unexpected and plays on the listener's knowledge of Jay Z's music. Plus, you wouldn't think Jay Z would get pulled over, would you?
