Jay Leno‘ He’s such a bad guy, he made a comedic appearance with an eye patch, a black eye, a bandaged wrist, and a swollen face… after taking a nasty fall near his hotel.

We had Jay arrive at the Comedy for Koby event in Beverly Hills on Monday night and our photographer asked him the obvious…what the hell happened to his face?!?

Jay tells us he was staying at a hotel on a hill and wanted to go to a restaurant at the bottom of the slope… and instead of taking a winding path down, he tried to take a shortcut… and it ended up he fell down the hill.

As you can see, the left side of Jay’s face is extremely swollen and bruised… and he has an eye patch and a wristband… but he says the incident hasn’t stopped him from performing at the Yaamava this weekend’ Casino in Southern California.

Jay says there were a few thousand people waiting for him to take the stage and he just couldn’t let them down… waiting until after his performance to get to a hospital.

The comedy legend has taken quite a beating in recent years… shattering bones in a motorcycle accident and suffer third-degree burns in a car fire in his famous garage.
