What movie am I thinking of(80s or 90s)?

There was a comedy movie(Steve Martin keeps popping in my head but that's probably wrong) in which there's a scene where a guy is asked either his SSN or maybe driver's license number and he responds with like "5" so the copy is waiting and says something like it's not enough numbers so the dude goes "42" and that goes on a bit before he just rattles off way too many numbers to the guy.

That's all I've got. I did the same to my daughter when she needed my SSN and I wanted to show her the clip but my fog-addled brain is failing to recall what movie it's from.
