Sounds like a version of shell game
whats the trick this time?
if you do it for 100 sec they give you counterfeit money?
it was legit ... in a nice neighborhood (where I live) ... with a big professional poster advertising the game and the rules ... run by a few harmless nerdy university students (guys & gals) ... and drew a big crowd.
they officially counted down the 100 seconds with the timer on an iPad for all to see.
the only "trick" is that the bar was thicker than a typical pull-up/chin-up bar which makes it harder to get a good grip.
I would've given it a go, but I completed a brutal back/delts workout a few hours earlier ... and I just came out of a restaurant having feasted on a huge dinner ... and I was wearing pretty good threads which weren't suitable for the task.
