When I was 22 I worked out at L.A. fitness in Diamond Bar, CA. Mark Mcgwire's brother Jay was a trainer there and really cool to me. Both of us knew this other white dude named Doug, he was about 5ft. 8in and was really strong, like 1400lb hip sled and 280lb military press. Anyways, one night this chicano gang banger type came in with his girl and Doug was upstairs talking with Jay and Doug gives the two a once over as he goes to the drinking fountain for a drink of water. The chicano guy says something to the effect "what you looking at my girl for" shit and Doug tells him to fuck off or whatever. So the chicano guy says hes gonna go to his car and get his gun (probably didn't have one but he's acting bad in front of everyone and his girl). So my buddy Doug just rocks this guy wis a jab to the head and knocks him cold out, his head hitting the wall by the fountain then he fell down. Well, Jay said he had to revoke Doug's membership for lawsuit reasons, and he did. The guy got up after a minute and left, never came back. Doug went to the L.A. fitness in Monclair/Pomona from that day on, I went to see him one night. Bad ass dude.
