Lloyd: This didn't come out of our travel fund.
Lloyd: Yeah, I was able to raise 25 extra bucks before we left.
Harry: Where did you get 25 extra bucks?
Lloyd: I sold some stuff, to Billy on 4C.
Harry: The blind kid?
Lloyd: [Laughing.] Yeah, yeah.
Harry: What did you sell him Lloyd?
Lloyd: You know, stuff.
Harry: What kinda stuff?
Lloyd: Few baseball cards, a sack of marbles, [coughs.] Petey.
Harry: Petey? You sold my dead bird to a blind kid? Lloyd, wh- he- wha- Petey didn't even have a head!
Lloyd: Harry, I took care of it.
At the beginning of the movie, Harry's van has bucket seats, yet later on when the "gas-man" rides along, he is sitting on a bench seat in-between Harry and Lloyd.
I think that this may be an in-joke. If Mary Swanson had chosen Lloyd instead of her fiancee and married him she would become Mary Christmas.
