I came across the following video while (somewhat) randomly surfing the web the other day:
Bill Herrington (the Speedo-clad bodybuilder in the clip above) is a gay porn star, by the way. Although he hasn't appeared in an adult movie since 2003, he's become something of a celebrity in Japan in the last few years thanks to the slew of mash-up videos (aka MAD movies) that have been posted on Nico Nico Douga, a Japanese video-sharing site.
Many of them, like the one above, are inspired by video games. This (rather NSFW-ish) one, for instance, is based on Final Fantasy VII.
