Look, to be honest, we're not too sure what game these kids are playing. But it seems to involve lining up against a wall while someone kicks a ball at your bum.
Still, one cocky-looking kid has clearly decided he's not bending over for anyone. He's just going to stand there, with his hand on his hip, and wait for the lesson to end so he can go to an actual lesson and learn about science or art or literature or something. (Actually, the more we think about this, the more we're on Cocky Kid's side.)
Anyway, you can guess what happens, can't you? But it's still worth watching the video above just to check you were right.
Enjoy sniggering at other people's misfortune, do you? Then you'll definitely enjoy all of these, too...
