I was just a bit too young to stay up for "Tomorrow," but I became a Tom Snyder fan during his CNBC show as well as the first Worldwide Pants "Late Late Show." I also loved that even as the times changed around him, HE never seemed to change. He's one of the handful of guys I'd see on TV and think "gee, I'd like to be like him."
I'd love to fire up a colortini/simultini, sit back, relax, and watch the pictures now as they fly through the air one more time, but all I have now are DVDs.
I wouldn't really consider the bit about them being in a mental instituion to be a LOST homage (especially since Buffy did a full episode with that exact motif first), but when Hodgeman said Greendale was purgatory, I'd considered that a reference.
