I remember Johnny Carson laughing effusively when I made my 'Tonight' show debut in the early 1970's as part of a sketch comedy group called the Ace Trucking Company. We didn't even have a name when we first did the show, but one of my favorite moments was looking over to see him laughing, falling off his chair. This was topped only by another kind of tribute often paid by Johnny: imitation. We did a sketch about tough motorcyclists stopping into a shop and demanding shoes and coming away with handbags and ruffled blouses and stuff, and after it was over, Johnny kept saying, 'I want some shoes,' like one of the characters, and that was just a kind of salute. To have him pick up a catchphrase and repeat it was just amazing.
