Football fan gets season tickets for getting HEAD tattoo

This level of SPORTS FAN INSANITY rarely pays off. Normally you'd just be a weirdo who's way too into football . . .

Last Friday, Pittsburgh Steelers receiver JUJU SMITH-SCHUSTER met a fan who had the team's logo tattooed on the side of his HEAD. And he asked JuJu to sign it.

So he signed the dude's dome. Then he joked about it with reporters and said he'd get the guy "any tickets to any game" if he turned the SIGNATURE into a tattoo.

The guy heard about it . . . and took it seriously. Before the weekend was over, he DID IT. The side of his head now has the Steelers logo AND a tattoo of the signature.

A writer for Bleacher Report posted photos, and asked JuJu if he was planning to make good on the offer. JuJu said YES . . . he got the guy SEASON tickets. 

Of course... he's got the tat for life... not so sure he'll get season tickets for life.
