What do Arthur and Erik do while Joey is at the Fisher’s house?

Sure enough, when Erik and Arthur come through the gate and see his friends, they start making fun of them for being farm laborers. Paul is furious but he doesn’t know what to say. He tells his friends to ignore them, but Tino stands up to Erik. As he does, Arthur takes his blackjack out of his gym bag. Erik tells him to put it away. But then Tino tells him that he saw his flop on the field. He starts to make fun of Erik. Erik hits Tino across the face so hard that Tino spins around before he hits the ground.
