I always wished that Gary Busey and Gilbert Gottfried would have

appeared more regularly on the show.

Although Gottfried is even better when he is directly interacting with others (for example, his Howard Stern appearances) or when he has time to build, but I still like him doing short quips a lot, too.

Busey was always hilarious just because he'd say such bizarre things. The reactions of the other commentators were priceless.
