6. 'Harold & Kumar Go to White Castle' (2004)
A candid portrait of the insanity of American society – disguised as a slapstick romp about two men on a quest for the right burger. Because some nights Burger Shack just won't cut it. Along the way, they face the question every stoner must ask at some point: "Dude, didn't we come here on a cheetah?"
Stoniest moment: The cameo from Neil Patrick Harris, who turns out to be an Ecstasy-crazed heterosexual: "It's a sausage fest in here, bro. Let's get us some poontang, and then we'll go to White Castle. . . . The 'Doogie' line always works on strippers!"
