There must have been dozens of times in Dallas where Bobby threatened to physically hurt someone if he didn't get what he wanted. There were also a substantial number of times when Bobby did physically attack someone, but it was almost always someone smaller, weaker, and/or older. Mark Graison is the only exception to that who comes to mind, but even with him, Bobby was pretty careful about what he did, since Mark was about Bobby's own size and age. The one time Bobby and Mark fought was at the Oil Baron's Ball, a fight Bobby knew would be broken up quickly, and he also had a lot of family right there to help him if things went badly for him. There was never a time when Bobby chose to fight Mark when there was nobody else around but them. Bobby and Pam were still married when Mark started pursuing Pam and Bobby didn't so much as throw one punch. He punched other, weaker adversaries for far less. Mark took Bobby's wife from him! If I'd been Bobby I would have kicked Mark Graison's ass every time I saw him for exactly that reason. Bobby punched people for far less than what Mark Graison ever did, but again it was almost always someone smaller, weaker, older, etc. Bobby's terrible temper was well known and people knew he wouldn't hesitate to start a fight, so a lot of the time, all Bobby had to do to get was way was threaten somebody. It was almost always exactly the same threat: "I'll take you apart" is what he'd say. Usually, "I'll take you apart" was a physical bluff that Bobby ran, over and over, to make people scared enough that they'd do whatever he said without him having to actually throw a punch. Just the possibility that he might follow through on it scared people enough that they'd give Bobby whatever he wanted. Using a physical bluff like that is typical of bullies, especially when they've already established a reputation for being violent. When that threat is coming from a big, strong guy like Bobby, it's intimidating. I think Bobby was a bully.
