-- Mickey Gall, the fighter who beat CM Punk in UFC, was at the WrestleMania post-show party with a lot of people saying he was acting like a jerk by screaming and not signing autographs. Along with his entourage, he created a scene to the point where "people were waiting for someone to get in their faces" but nothing happened.
-- Gall was irate and screaming at people outside the party as well until security came and he and his group then calmed down with no confrontation from anyone. The party overall was said to be by far the tamest one in many years.
