When I was in college, some students decided to try to get enough people to break the largest leap-frog game record. The problem is they tried to do it on a Saturday morning, and of course 75% of college students sleep until lunch on Saturday. So they decided to reschedule it for 11:00 during a weekday. I, for the record, didn't participate because I would have been late to a class I couldn't afford to miss. Long story short, they had enough participants to break the record, but when they sent the required photos and videos to Guiness they found out they weren't properly "leap-frogging." I think they were illegally touching the ground with their hands, or some minor detail like that.
