Jay Leno may have a future in competitive eating ... because he's the latest Fatburger XXX challenge champ!
The challenge is both simple and daunting ... devour an entire three-patty, 24-oz Fatburger with all the fixins.
Jay scarfed it down in 5 minutes flat at the new Bev Hills Fatburger. For that he got a certificate.
Jay joins an impressive list of gluttons, including the record holder who scarfed down a 16-patty, 128-oz monstrosity in 35 minutes.
As for Leno ... a little Jaywalking is definitely in order.
