Don't worry. The video above is definitely safe for work. It doesn't so much feature William Shatner's penis as much as it features Shatner talking about his penis, which all nerds of appropriate ages should be able to enjoy.

If you didn't catch Shatner's appearance on last night's Tonight Show with Conan O'Brien, please stream the clip now. You'll learn how Captain Kirk likes to "rip it" on the 101 and turn the Vulcan salute into an obscene gesture. Spock would not approve.
