I watched Brokeback Mountain on Friday. I was thinking about this thread, so I paid close attention to the Jack/Jimbo scene. Here is my take, and it may well have been already discussed:
1. Jimbo got uncomfortable after Jack's lingering stare. Jimbo looked away, then to the bar tender or staring off
2. He made the buckaroo comment, got up, put his money down, and walked away toward the group of guys over by the pool table
3. Jack turned on his stool and watched Jimbo walk away
4. Jack remained turned, watching Jimbo and the guys. At that point, the bar tender leaned forward and said, "you ever thought of calf-ropin'"?
IMO, what the bar tender was saying was something to the effect, 'you ever thought of trying to get a girlfriend' instead of coming on to guys. Jack didn't get it, and thought he was referring to calf-roping, which does require a good ropin' horse. They are very expensive.
Amazing how, after watching BBM for so many times, I still get little bits and pieces.
