Failing that, at least wear a shirt. The rando who took the stage right and got in the face of newly-crowned Ultimate Marvel Vs. Capcom 3 champion Christopher "NYChrisG" Gonzalez followed neither of these suggestions, and was escorted out by security for his trouble.
To be fair, it's unclear what the shirtless man who hopped the stage was challenging NYChrisG. Maybe he just wanted to show the new champ his controller. Maybe he was admitting his undying admiration and respect. Whatever the case, it wasn't the time.
Congratulations, Mr. Gonzalez. You've worked long and hard for this. Sorry about the random weirdo.
