My favorite episode is "46 Long," the second episode of Season 1. It just has so many great things--Paulie's line about "this espresso shit," Livia accidentally starting a fire in her house and telling Tony "I'm not dead, unfortunately for some" when he comes to see her and give her flowers, and the funny subplot where AJ's science teacher, Mr. Miller, gets his Saturn stolen and Tony sends Paulie and Big Pussy to get it back. And there's also the scene where Tony screams at someone in the Bing who doesn't know how to use the phone correctly: "You press hold, g*d damnit!"

Great episode!
