Pogo Stick goes to Shovel as Pain Goes to Balls

My best guess is that these two were thinking that something else other than severe ball pain was going to happen. What that was, I'm not sure. Think about it. What exactly were they thinking was going to happen? Jumping on a pogo stick to hop onto a shovel with some fat geeky dude standing over it.

Of course there was going to be some type of ball pain!
