Okay, in one epidsode Joey sees a "hot" girl from Monicas apartment. He waves at her, then tries to count the number of windows over he is. One time he is looking for her by Ross's apartment he asks Ross, gets mad, asks his neighbor, then turns and runs down the hallway. If you look closely, when Joey is going to Ross's apartment, it's a dead end. Then Joey runs right into the dead end, but this time it's a hallway!
