The Packers' rivalry with the Vikings got an extra jolt this week when someone decided to include a Vikings jersey inside of Brett Favre's locker at the Pro Football Hall of Fame.

Although Packers fans were upset that a Vikings jersey made its way into Favre lockers, hopefully they weren't too mad about it, because things definitely could've been worse.

For instance, someone at the Pro Football Hall of Fame could've tried to sneak the jersey below into Favre's locker, which probably would've started a small riot in Green Bay.

Surprisingly, this picture wasn't taken in Canton, Ohio. It was taken at the Denver airport. The only way that jersey could get any better is if we found out that this guy is related to Favre.

Anyway, if you're going to buy a personalized jersey, this is definitely the route you want to go.

Basically, this jersey kills two birds with one purple-colored stone. Not only does it let everyone know that you're a Vikings fan, but it also lets everyone know that you hate the Packers. On the other hand, that's already kind of implied if you're wearing a Vikings jersey.

If this guy wants to be a billionaire, he'll be selling these jerseys outside of U.S. Bank Stadium before the Vikings' home opener, which just happens to be against the Packers.
