Lonely Island's "Jizz In My Pants"

Yeah, with 20 million views, I know I'm not exactly the first person to think this is funny, but this thing really made me laff the first time I saw it. I don't know if it's the unnecessary British accents, the fact that they always blame the girls afterwards, or the ridiculously high production quality on what's essentially an homage to splooge, but whatever it is I must have watched this a hundred times. Possibly NSFW.
