It’s not me. It’s my alien hand. In fact, sometimes my whole body feels alien.

Gwen: I’m sorry George.
George: I don’t understand. Things were going so great. What happened? Something must have happened.
Gwen: It’s not you, it’s me.
George: You’re giving me the “it’s not you, it’s me” routine? I invented “it’s not you, it’s me”. Nobody tells me it’s them, not me. If it’s anybody, it’s me.
Gwen: All right, George, it’s you.
George: You’re damn right it’s me.
