What happens when El Genius encounters Armpit in the hotel?

Armpit heads for Kaira's room, but he is stopped by El Genius, who reintroduces himself and invites Armpit, much to Armpit's surprise, into his room. There, El Genius insists that Armpit take a couple of swings with what El Genius says is a souvenir baseball bat. El Genius finally lets him go.
