WHY GOD CREATED YOUTUBE™: Pernell Roberts, Karate Master

You haven't lived until you've seen Pernell Roberts, star of the shockingly long-running M*A*S*H spin-off Trapper John, M.D. slice a watermelon in half with a sword -- on a leotard-clad man's bare chest.

Oh yeah, and Bea Arthur introduces him.

WHY CAN WE NOT BUY CIRCUS OF THE STARS ON DVD YET?

Truly, this is why God created YouTube.
