It's always refreshing to see a celebrity have a sense of humor. And, it's pretty funny when they can laugh at themselves. This video right here is really quite funny. Have you ever wondered how a professional singer would perform in front of a karaoke crowd? Well, Jewel puts a little bit of a spin on it, which includes a disguise and a new name of "Karen". I don't want to ruin the video for you, so I won't tell you what happens, but, it's pretty good.
