In the scene where Deuce is walking with the tall women and the phrase "freak" is shouted, the speaker of that line is actually Adam Sandler. Other than being a producer, it's his only "credit" in the film.
Even though Norm MacDonald was not in the official credits, he was given credit in a roundabout way at the end of the movie. A cut was shown of him as a bartender saying that Norm MacDonald only worked one day on the movie.
When Deuce first meets Antoine and sees his weapon collection, Deuce says "I collect Canadian quarters...I got about six of them". After his first "job" when he goes to the bar, his bill totals to $11.50. He gives the bartender "Ten, and six quarters", presumably his Canadian quarter collection and total take from his first "job".
Also of note, the bartender, Norm MacDonald, is indeed Canadian.
