This may sound like kind of a strange question, or a VERY strange question,
and I'm sort of embarrassed to even ask this, but I hope someone could help me.

Hypothetically, if many Different MEN are falling from the sky, you'd say "It's raining MEN" in plural. But if it's just one same MAN falling from the sky in many different clothes, how do you say it?

For example, imagine it is raining men right now, but all the men are just one same person named Mark, only in different clothes, then do you say "it's raining Mark?" or "It's raining Marks?"

Any help would be really appreciated!!
Many thanks in advance!
