Paulie, Silvio and Tony try to persuade Artie Bucco to employ Furio to make things easier with immigration.

Tony: This kid, that's all he does, makes buffalo
mozzarele 24 hours a day.

Artie: So, he's a master cheesemaker.

Silvio: Yeah, so's Paulie!

I love that one because the joke is at Paulie's expense for a change.
