1.8 "The Hobo Code"
Inside ad agency Sterling Cooper, three operators connect calls and listen in. One of them Lois, played by Crista Flanagan (right) has developed a crush on Salvatore Romano (Bryan Batt), the firm's closeted art director.

Lois: "Ciao Ciao". [smitten] My stars!
Operator #1: Two weeks in, she's already a goner.
Lois: He talks to his mother a lot.
Operator #2: Because he's not married.
Lois: He's in the art department? Well, what does he look like?
#1: Did you see that movie Marty with Ernest Borgnine? He lived with his mother.
#2: Stop teasing her.

Later in the episode, a gay client Elliott (Paul Keeley) who is staying at the Roosevelt dangles a carrot for Sal.
I was in the lounge last night... and I end up having a drink with Robert Mitchum! Actually many drinks. [laughter]
