Carnies generally do not have any f**ks left to give. I believe they were born without any at all. This carnie decided that he was going to mix business with pleasure and watch a porn while operating a ride. You could say he's watching two rides. You could also say he's enjoying some "ball and bucket". He's hoping to see a ball go into the hole for a prize, whacking a mole, filling the clown's mouth with water... and so on. Basically this guy is watching porn in front of a bunch of kids. The kids come off the ride raving about how much fun it was! So they didn't notice a thing thankfully. The moms however, they weren't having it. Listen how they frantically call their kids over.
