To show you what not to do, each Friday STACK brings you a moment from the weight room or sports field gone horribly wrong. This week, we have an oldie but goodie.

With jack stands subbing for weight stands, a spotter wearing the classic socks/sandals combo and shaky exercise execution, this video has the potential for all sorts of bad things to happen. We’ve gotten pretty good at predicting what will go wrong in these things, so we spent 37 seconds waiting for this kid to choke himself with the bar, put a hole in the wall or throw up.

Much to our surprise and delight, none of those things happened. Instead, we got something even better.

Animal videobombs and photobombs are the best. Here are 10 more of our favorites, just because.
