The only sport I don't like to watch is basketball, though I do like watching certain players. I still don't go out of my way to watch it though. We probably had that conversation already.
I never really tried watching golf. I could imagine someone who's really into it watching closely for technique, but it's hard to imagine it has many non-hardcore fans (e.g. the way football does); more of an all-in or all-out thing.
If I'm at a bar not drinking (because I don't drink...so, sipping tonic water or something) and there are a bunch of TVs on and nobody to talk to and nothing else to read or look at, and each TV is showing a different sport, then my ranked preference is for Olympic trampolining, baseball or hockey, tennis, billiards, football, soccer, rugby, cricket, basketball, and then stuff like golf, motorsports and track&field and other things that are just simple contests to see who can go the fastest/highest/throw the thing farthest/etc., then stuff like bowling or darts that are really just games you're supposed to play while drinking, and then at the very end stuff that needs judges like diving and figure skating and gymnastics. (This bar has a lot of TVs and a killer cable package.)
