How many degrees of separation between THIS show and THAT show?

I remember Bacall on Rockford. Didn’t know she’d been on Sesame Street, but I’m not too surprised; it ran for ages, and I think Bacall lived in Connecticut. She could bring a touch of class even to Oscar’s garbage can.

You’ve got to admit, though, the Emmy thing was a nice bit of trivia.

lol what about the greatest “guest starring” show of them all murder she wrote … I mean it had almost entire casts of shows as guests stars(the only 2 of the main cast from mash that didn’t appear on the show was Alda and the guy who played radar ) … of course, the creators first mystery show was also known for its guest stars "Colombo "

The Goldbergs had a guest appearance by James Lipton (yeah, that guy, he played “Lotzi”).
IMDb lists 7 people who have appeared on Inside the Actors Studio and The Goldbergs, for example Drew Barrymore(!).

Note: this is NOT a loop.

The Goldbergs need to shorten this by one by having Lipton guest star on the show. (IMDb doesn’t list any such crossovers.)
