When Hue drops the trash into the dumpster (just before Carmela shows up), part of the name on the side is taped over to create the words 'LA LAW'. The actual name of the waste management company was Laidlaw Waste Systems. Laidlaw later became the Waste Management of Canada Corporation -- whose telephone number still ends in 7800, just like the number on the dumpster.
Tony: I don't think men are pigs. Do you?
Lucille: Pure pork sausage, baby.
Tony: Hey Stan, how'd you like to go on assignment? Undercover.
Stan: Me? Really? Undercover?
Tony: Very deep.
Stan: Narcotics? Vice?
Tony Scali: You know, David, I come from a different time. It was easier to believe that people did things for reasons other than money, because they wanted to help, because they loved what they were doing. There wasn't a doubt in my mind that Yogi Berra would have played baseball for free. I feel bad for kids your age, David. It's so hard to have a hero. Someone you can count on for the right reasons. Someone you can trust. There's no one left.
David Scali: There's you. I think you love what you do. I mean, you don't get paid any money to be a dad. You don't have to hit home runs to be my hero. And you don't charge so much for autographs.
Tony Scali: They get their name from that, uh, Duvall line from Apocalypse Now.
In the 1979 movie, the line "Charlie don't surf" comes just before the famous "Ride of the Valkyries" scene with the helicopters.
Stan: Stellars! Stellars!
This scene is a takeoff on the famous Marlon Brando scene from A Streetcar Named Desire when he yells, "Stella! Stella!"
