This guy's comedy routine can't compete with the guy in the middle - he's the videographer's dad and that's his real laugh.
Anita of Say No to Crack found this the funniest YouTube clip I've seen in a long time. Highly recommended. Hit play or go to Link [YouTube] - via Say No to Crack.
(he seriously has a laugh that has resulted in paramedics being called, us kicked out of restaurants, and of course, lots of pointing and staring)

But that. Made me laugh so hard I came very close to peeing my pants.
