Negligent Sex

Attention champdaddy: please be sure your liability coverage is paid up.

(story from Volokh)

the defendant did vary slightly the position previously used, without prior specific discussion and without the explicit prior consent of the plaintiff. It is this variation that the plaintiff claims caused his injury [penile fracture]. . . . The plaintiff's injuries were serious and required emergency surgery. He has endured a painful and lengthy recovery. He has suffered from sexual dysfunction that neither medication nor counseling have been able to treat effectively. . . .

Hardware Wars

Several people have pointed out Store Wars (Flash video).

Hardware Wars, the original parody dating from the first months of Star Wars is cruder but funnier, with a drunken Obi-Wan, real buns in Princess Leia's hair, and the cheapest special effects ever seen. The Atom Films site has the preview, but the full film is only available on DVD. Since it's worth about 98 cents, I won't be buying it!
