Gotta go back in time - whose standup bit?

I have a vivid memory of a standup bit that was punctuated by the refrain “gotta go back in time” from the “Back to the Future” theme, but for the life of me I can’t remember whose bit it was. Does anyone remember.

SNL? There’s a skit where Kevin Nealon and someone else (Dana Carvey?) are on an elevator with Michael J Fox. They’re big fans but MJF is just trying to go about his life. The only thing they can think to do is sing “Gotta go back in time” or “What would you do baby” in high pitched voices.

Yes! That’s the one! You won’t believe how happy this has made me.

Are you still “master of your domain?”
