The refrence to 3:00 comes from season 2. When Chris gets shot outside the Diner he comes to and asks for Tony and Paulie and tells them he went to Hell. He tells Paulie that someone (Mikey Palmice, I think) said to tell Paulie 3:00. He stays up over the next few episodes with his Girlfirend. Very interesting to see this come up agian I think. As well as the numerous mentions of Adrianna Lecerva "one moo ya hottie"
