I am reminded of a long-ago attempt I was a part of to break the record for playing basketball without stopping and without subs, which I think at the time was 50-some hours. It was during my home town's 100-year anniversary.
The definitions of the Guinness rules were pretty much indecipherable. The big debate was about break times allowed. We realized the previous records had been set in gyms closed to the public, which meant all kinds of shenanigans could have occurred because Guinness reps did not have to be present on site at the time. All you needed were witnesses and affidavits. Some guys were up for "cheating" by resting more than technically allowed when the gym was closed to the public. Others wanted to make the attempt without cheating. Other people knew the attempt was doomed to fall short, so when the public was in the gym, they showed off by scoring a bunch when that was not really part of the plan. It was a mess.
