A lesson in laughter

For all of you aspiring actors out there like me, take note in the following clip.

This is how an actor/actress laughs at something that isn't funny at all.

However with the reaction of veteran actors such as Ving Rhames, Keri Russell, Lawrence Fishburn, and Phillip Seymour Hoffman you would think that Tom Cruise's impersonation of a blackberry user was funnier than Eddie Murphy's "RAW."
