Surprisingly, Neil Patrick Harris' most memorable role is playing Neil Patrick Harris, albeit a highly unsavory, somewhat evil version. You want to party with the real life Neil Patrick Harris, but a night out with his Harold and Kumar counterpart is likely to end with everybody getting shot. NPH has the power to shake something like that off, but you probably do not.

Neil Patrick Harris not only owns these Harold and Kumar films but raises them to an elevated degree of absurdity that almost single-handedly justifies their existence. Never underestimate the power of a wholesome face spouting horrible profanity.

Also, the best way to celebrate NPH day is by re-watching this R-rated role! A Very Harold & Kumar Christmas is now out on blu-ray and DVD.
