Robin: Don Ho! What are you doing here?
Don Ho: Well, I came back to get some land we lost back in Hawaii.
Batman: And to do a little singing here in Gotham, I hope.
Don Ho: And I brought my most important prop along. It's gotten me as far as your Bat-Ropes have gotten you. Hey, I think I'll introduce Bat-Ropes in Hawaii. Pick coconuts more easy that way.
