All of these singing competition shows on the air and I caught a Jimmy Fallon bit that just made me laugh so hard I got an ab workout. Jimmy's idea, we all sing with headphones one and don't always sound good because we can't hear ourselves, now, let's mess with the pitch.

With Jimmy Fallon leaving his show in a year, I have been watching some of his bit and I though this one was funny. Check it out, how would you do?
