Quote from Chandler in The One with the Ick Factor
Rachel: Well, last night, you seemed to know your way around the table. Ross: [chuckles] I love it when we share. Chandler: You okay? Ross: I can't believe you two had sex in her dream. Chandler: I'm sorry. It was a one-time thing. I was very drunk, and it was someone else's subconscious.
