I was recently watching MST3K Ep. 0422: The Day The Earth Froze, which is good until the part where I get bored and do something else. Seriously, I hear it's a great episode, but I didn't have it in me to actually sit through it.
Nevertheless, the opening was of a short called Here Comes the Circus, which is horrible and well-lampooned. During the shot below, they exclaim, "hey, it's C. Everett Koop!"
And I had no idea who the hell C. Everett Koop was until I watched episode 5 of Da Ali G Show.
He's the bloke on the right.
I know him from health class in elementary school and junior high. He hosted lots of informational videos.
I still say that Abe and Ali G would have a great time hanging out!
