If you need a good laugh, here you go! It's pretty self-explanatory but check these guys out! They start off with sounds as if they're hitting a ping pong ball but then they start getting really into it! They're running around, "hitting" the ping pong ball until one "player" loses his footing, falls (and I'm assuming) loses the imaginary game.
I can't stop watching this video, honestly I keep cracking up! I want to join them in a game one day!
