Malaprops
Just finished watching the series over the past few weeks. Some of my favorites:
Chris (re Jackie Jr.): "He is the hair apparent."
Carmine Jr. (to Tony): "I heard about your alteration with Coco."
Paulie: "He's the Chinese Prince Matchabelli."
Johnny Soprano: "She's an albacore around my neck!"
Carmine Jr.: "We're in a stagmire."
Tony: "...prostate with grief."
Tony: "...the death of Vito Senior and all that entrails."
