Contrary to advice once given him by New York boss Carmine Lupratazzi, Tony is seen wearing shorts at the party.
When Tony arrives at the house for Hugh's party, he responds to Carmela's complaints about his tardiness by reciting, "Pins and needles, needles and pins". This is a line recited by Ralph Kramden in an episode of The Honeymooners, which in turn references the nursery rhyme: "Needles and pins, Needles and pins. When a Man marries his Trouble begins".
Yet another scene where Anthony Jr is playing his drums. If you take notice, in all the episodes where he's playing, it's always the exact same drum beat being practiced.
The movie Junior is watching is the Fellini film "La Dolce Vita" (1960). Junior references the opening scene, in which the statue of Jesus is flown over Rome by helicopter, with the comment: "You could tell it was a dummy." The film follows a journalist writing for gossip magazines, over seven days and nights on his journey through the "sweet life" of Rome in a fruitless search for love and happiness.
Angelo, Tony B, and Rusty (played by Frankie Valli) meet at The Four Seasons Restaurant (formerly inside the Seagram Building in New York), a subtle nod to Valli's famous band.
