Help me find this cartoon/comic

A guy I used to work with had a full page, single panel cartoon taped up on the inside of his locker door.

It was a birdseye view of a mens restroom. A man was in a booth, sitting on the toilet reading a newspaper and smoking a cigarette. Another man is seen having just burst through the bathroom door running towards the booth with his hand over his mouth like he’s going to puke.
The thought “what happens next” is certainly awful.

Because of the content I always thought maybe it came from an adult publication like Playboy but I could be wrong. I never asked him. But I’d like to get a copy of it. Anyone have any ideas how I could find it?

How big was the page, and what kind of paper? Single panels covering whole pages might narrow it down because I think that’s unusual.

It was definitely out of a magazine, that slick glossy paper. So it was the size of a magazine page. Not that uniusual for mens magazines.

My first guess was National Lampoon.

Do you remember if it was pen, brush, or something like charcoal, like the Addams cartoons? Black & white or color?

It was in color. Nothing fancy, just a cartoon.

I forgot about that. Could be. Could be.

Sergio Aragonés used to get an occasional full page color panel in MAD and the gag in the OP with no dialog sounds right up his alley.
