Watch the R-rated trailer for Knocked Up, Judd Apatow's forthcoming comedy. All your favorite Freaks, Geeks, and Undeclareds are going to be movie stars. Katherine Heigl too, probably. If you click on only one of these links, make it this one. (via)
I thought I would never see another recut trailer parody worth watching till the end, but I was wrong. This is really good: When Harry Met Sally as a horror film by John Piscitello.

The orgasm scene in Katz's Deli doesn't exactly work but they couldn't very well have left it out.
Speedometer videos scare the crap out of me. (via)
