I don't think my dad was a bigtime tough-guy until he got into fights. He has told me all of his fight stories and he seems like he was a pretty bad dude, even in the fights he lost. He told me he got in a fight with this one guy that just wouldn't give up, no matter how bad my dad would beat him. He said finally he just got sick of it and one time he tackled him and got up real quick and jumped on his leg over and over again, breaking it pretty badly. Apparently the guy stopped fighting after that. haha
I remember when I was younger... maybe 10 or so... which would make him about 54 or 55, we were driving down this street with a speed limit of 25, and the guy in front of us was going about 10-15mph. So my dad sped around him on the left (one lane each way, double yellow), and as we went around, this guy yelled "ASSHOLE!" out the window, and pulled into a driveway. My dad hit the brakes, turned around, got out and walked aggressively up to the guy, ready to fight. The other dude backed down real quick when he saw my dad coming.
Never saw him like that before or after that. Kinda upset me back then, but when I think about it, I always laugh.
My dad rules. Love him to death.
