This is very probably one of the scariest places you can park your bum: at the very edge of a corner of a very tall building in downtown Toronto. To make it even worse, Oleg Cricket, the guy in the video, decided it would be a perfect time to start spinning around while he’s sitting too. I’ve never been so stressed out after watching someone sit down.

The other tricks he pulls in the video are just as gnarly so make sure to do your breathing exercises before and after you watch him be a crazy thrill seeker.
