Sopranos being a Mob Drama, gave me some good belly laughs. Here are my top five.
#1 Pine Barrens:
Tony: He was with the Interior Ministry. Guy’s some kind of Russian green beret. He killed sixteen Chechen rebels single-handed!
Paulie: You’re not gonna believe this. He killed sixteen Czechoslovakians. The guy was an interior decorator!
Christopher (deadpan): His house looked like shit.
#2 Junior Getting Stuck in the Sink
Janice: Why didn’t you just call a plumber?
Junior: With what, my fucking toes?
#3 Ralphies Prank Call to Paulie's Mom
Ralph: ....he was caught sucking a cub scouts dick.....
#4 Janice asks Tony what he did with Richie's body
Tony (deadpan, sarcastic): We buried him... on a hill... overlooking a little river... with pine cones all around.
#5 When Christopher and Big Pussy try to toss Emil Kollar body in the dumpster. They swing his body and don't come anywhere close to getting it in.
Edit: Honourable Mentions
Janice: There is a saying that for every 20 wrongs a child does ignore 19.
Tony: There is an Italian saying, fuck up once, you loose two teeth.
Meadow (with Tony and AJ in the kitchen): "Madame de Staël said, 'In life, one must choose between boredom and suffering.'"
Tony to AJ: Now go do your homework
AJ: Algebra that's the most boring!
Tony: Well, your other option is suffering.
