Stepping to promote his new film "The Monuments Men," Matt Damon appeared on "The Tonight Show with Jay Leno" last night (January 14).

During the interview, the 43-year-old actor discussed practical jokes played on set with George Clooney.

"I was working out and my pants [were getting tighter]- I said this just can't be," Matt explained. "I read finally, which answered lot for me, that he'd been taking my wardrobe in [and had my pants slowly adjusted] about an eighth or a sixteenth of an inch."

He continued, "I never said anything to him, which he probably loved even more."

In regards to his recent injury that resulted in a broken collarbone, Mr. Damon stated, "Apparently I'm not a very good mountain biker. The bike stopped - and I didn't."

"I probably was showing off a little bit, yet," he added.
