Jonah Hill -- I'd Totally Iron My Balls ... Maybe

Jonah Hill is taking a page out of the George Clooney scrotum-grooming manual -- telling TMZ, he'd totally consider getting his ball bag ironed out to remove the wrinkles.

A little background ... Clooney's joked over the years that he'd gotten some unique cosmetic work done: "I did get my balls done ... I got them unwrinkled. It's the new thing in Hollywood -- ball ironing."

Clooney was obviously kidding ... but the comment JUST inspired a real-life cosmetic procedure called "Tighten the Tackle," which uses a real laser to tighten up excessively loose scrotal skin. (Note: scrotal skin is supposed to be loose)
