It's Case Keenum's 10th training camp, and if there's one thing the veteran quarterback has learned ... it's the value of a good prank during the dog days of camp!
The Bills' backup QB decided to have a little fun at the expense of his teammates as they prepare for the start of the season, dressing up as a fan, and bugging players for autographs.
"I'm going to see today how many autographs I can get from my teammates," Keenum said in a video posted to the Bills social media page.
34-year-old Keenum looked the part ... he rocked a Bills shirt, sunglasses and a tan bucket hat. Case was able to snag a few autographs ... and his undercover person was so good, he nearly got wideout Isaiah McKenzie twice.
Luckily, when Case approached McKenzie for a second time, he realized it was Keenum.
