Parkour by PhilyDee and Kie Willis

I'm just really, really curious how the last guy in the first clip wound up getting down from that window.

I was torn between watching them climb a wall and looking away for fear of seeing their teenage buttcracks. You'd think saggy pants would actually pose a danger in those routines.

Anyway, the second vid was just horrifying.

As a person involved in building maintenance, what I see here is a lot of damage being done because they're too ignorant and selfish to think of the consequences of their actions. See how our hero slams his weight into the finely carved stonework of a fifteenth century church. How many repeat impacts before pieces break off?

The church is St Mary the great, Cambridge,by the way. http://www.gsm.cam.ac.uk/
If the idiots are students, then this video would be enough to end their university careers.

Yes, I'm impressed at their athletic skills, but the structures they're slamming into, jumping off, scrambling over, are not, in the main, designed to take the loads they're imparting without damage.
Yet they won't even know it, when the repair bills start coming in.

I'm thinking stuntman or cat burgler as career choices.

Imagined everyone of them had the audio edited, so we didnt get to hear the high-pitched, childish voice: "Look what I can do!!" lol
