Kids Test Hockey Equipment in Background of Teammate's Interview

The headline for this video on Reddit is simply “Kid answers questions about hockey.” I have no idea why I clicked it, but I did and holy crap it’s the funniest thing I’ve ever seen in my life today. Some little kid is literally talking about something on camera. It doesn’t matter. What’s happening in the background can only be his teammates testing out their new equipment by bashing some kid’s helmet off the glass over and over and over.

I’m just going to assume this is all in good fun because there are adults around and someone would stop it.
