CBS Mailbag: Dave And Paul's NBC Flashback | Letterman 

An NBC flashback and an Alan Kalter punch, with Buzz Aldrin making a cameo. Marvelous.

I wonder if the old NBC sets were made for the Man of the Moon Letterman Jerry Lawler scene. Man on the Moon was released Dec. '99

"A kink in the air hose" -- OMG!

I think it would have been funnier if Alan had beat up the cardboard cutout from the first gag.

I think there's a mistake on your air date. Clearly this is from 1986.

Alan's bloodlust was so all consuming, he ignored that poor admin assistant.

Boy I thought that last skit was gonna end way differently than it did, haha

I'd love to see a compilation uploaded of Hairpiece/Not A Hairpiece segments

I love all the Late Night stuff you guys have been posting, but I’ve really been wanting more Late Show videos lately, so thanks! How about some Rupert Jee videos??

love dave miss him

On the program tonight, from "Everybody Loves Raymond", Ray Romano, and comedian Jeff Altman. Stay tuned, we'll be right back.

Still hoping to see the Annual Spring Parade from 1985!

Brilliant top of his game

Great bits.

Alan must have been tall. He was eye to eye with Dave, who is 6'2''.

2:23 a few months before his actual bypass surgery

Show me the dog. Show me the dog!

The Audience doesn’t recognize Buzz Aldrin.

Will Smith must have watched this

Alan Kolter Tony Menendez and Will Smith ALL on the Letterman Show. Hmm

Buzz American hero, sure
