Dave opens up with talk of the NBC affiliates' convention, at which it was agreed that all late-night programs would begin Monday through Friday at 11:35 P.M. starting the next season. All that affiliates' talk was lost, of course, with Johnny Carson's late cameo.

Don Novello of ""SNL"" fame promotes his new one-man show off-broadway; Dave welcomes the recently reunited Procol Harum.

Included: ""A Day in the Life of Laurie Diamond,"" showing Laurie's many (bogus) responsibilities as Dave's assistant: getting him breakfast (a bucket of soft-serve ice cream); signing for daily fudge deliveries; helping Dave with his ""Golden Girls"" scrapbook; helping him get his hand unstuck from a cashew jar; finding his shoes; avoiding his ""mom;"" playing a prank on Willard Scott; answering his fan mail.
