Quote from Sam in The Improbable Dream (Part 2)
Rebecca: Sam, I need to talk to you. Sam: What's up? Rebecca: Well, it's a personal thing about my relationship with Robin. I haven't told anybody, but I need somebody to talk to. Sam: Oh, no. He's married, isn't he? Rebecca: No. Sam: Gay? Rebecca: No, no, no. Sam: Well, what is it? You can tell me. Rebecca: All right. I think it has something to do with this. [After Rebecca peels of her face to reveal Al, Sam wakes up in bed:] Sam: I hope that was a dream.
