He’s a real stand-up guy.

Comic giant Gabriel “Fluffy” Iglesias gave comedy club staffers thousands for making them work an extended shift, we hear.

Sources said that the “Masked Singer” guest judge dropped by Gotham Comedy Club for a last-minute set last week. Iglesias gave a bumper performance, lasting nearly two hours and forcing the staff to stay late.

But the comic left $3,000 among the workers to make up for it. Reps for Iglesias and the club didn’t get back to us.
