Jennifer Aniston, Demi Moore, Charlize Theron and Drew Barrymore had fun rapport with Letterman, but perhaps none more than Julia Roberts, who was known to plant a kiss on the funnyman's lips every now and again.

"We can all remember of course his relationship with Julia Roberts, you know, and she flirted right back," Schaffer said.

Letterman's not the only one who saw some action on the show. Schaffer remembered Barbara Walters being very friendly to him during one of her earlier appearances.

"The first time Barbara Walters came up she gave me a big kiss," Schaffer said.

ET first visited Letterman and Schaffer 32 years ago when the show was still on NBC. Even then, Schaffer was shaping his legacy.
