my dad almost got into a fight at the Cards baseball game about a dozen years ago. Some jerkoff threw beer from a couple rows up, drenched my dad. Not sure what he or who he was throwing it at, never found out (from what i got from it, he acted like it was an accident), there were no problems in our section till then.
Anyway, my dad hops up, 2 other spectators point out the guy, and my dad goes up and grabs at him, the guy hops over a seat, by that time, people start stepping in. I try to get hold of my dad, don't want him to go to jail (unlke me, my dad's a hot head, and loves a good fight. still does at 64 yrs old).
This goofy SOB that starts it turns chicken and threatens to call the police on my dad. Dad replies," You can call 'em after the fight!!" About that time, security and vendors are on the scene, everybody's coming to my dad's defense and the guy (lucky for him) gets tossed from the ballpark.
Another time when i was a kid, my dad almost got us kicked out of Holiday World (amusement park) because he accidently flung his arm back while making a point and knocked someones kid down.
