How about a few more.
MLB Grounds Crew Member: Once a game you throttle up a lawn tractor and do doughnut around the in field (And which of us would not pay to that at least once?). Or your swapping out base pads. Sure you have to roll out the tarp if it rains, but the 99% of the time you are not doing that your watching games for free.
Team Rep in New York for the NFL Draft: I'm not even sure that I even need to explain this one. What work does this person actually do that day? You have to think that the night before, during, and after are just cherry. Careful you don't show up so (hungover) that you forget how to write.
Boxing's Round Card Girl: O.K., this is a ladies only item, but seriously is there a more affirming moment in all of sport than when those girls enter the ring. With zero chance of even breaking a sweat they get as much cheering as those guys cheating death 3 minutes at a time.
Flag bearer during the opening ceremony of the Olympics: You know the ones who carry a country's flag leading that nation's athletes? Think about this...the Jamacian flag bears can claim to have beaten Usain Bolt around the track on foot. Talk about a "Hi Mom" moment. Short of becoming "that guy" by tripping and impailing yourself on global T.V., your instructions are as simple as driving directions in a NASCAR race.
