When Cliff calls Caroline's father, Cliff simply picks up the phone and starts talking to her father without dialing any numbers!
Caroline brings a sleeping bag along with her, claiming that Rudy's beds are too hard for her to sleep on, but when Cliff comes in to check on her after she tells him she wants to go home, she's sleeping in the bed she said was like rocks, and not in her sleeping bag.
Rudy: Dad, you will do your impression of the funny pirate, won't you? Everybody loves it when you do the pirate!
Cliff: Well, first of all, I am not a professional comedian.
