[TOMT][movie][quote] looking for a quote, possibly by Michael Caine, from a movie or series.

This has been bugging me for years and I don't seem to get it figured out by myself.

The quote I'm looking for is: "And while you're at it, live a little." For some reason I vividly see Michael Caine saying it with a mellow voice. I immediately thought it would be a quote from the Batman trilogy but this doesn't seem to be right. Have been looking for other Michael Caine movies, but this didn't turn anything up either.

I don't really have a lead on the period this movie or series would have aired, but presumably it could be 2000's and up.

Could anyone help please? Thanks so much in advance!
