The Austin Powers films love their crude, raunchy humor. They also love getting celebrities in on the joke. After all, what's funnier than having some of your favorite stars make cracks about male genitalia?

For example, take the extended gag in The Spy Who Shagged Me, when Dr. Evil launches a rocket that's shaped like a huge, well, you know. As people around the world marvel at the phallic weapon soaring above the planet, we're treated to several cameos ... of famous stars whose first names all double as euphemisms. For example, there's, uh, Willie Nelson and Woody Harrelson, both gawking at the genitalia-shaped weapon passing by.

The gag comes back around in Goldmember, and this time, the Osbourne family shows up. Only the rocker and his clan aren't too happy about it, and they break the fourth wall, criticizing the third Austin Powers movie for lazily reusing the joke and dragging them into it. But while they may call it lazy, we think these randy little cameos are pretty hilarious.
