Dick: You know, I had such a great time with Mary today. In the past, there's always been this human-alien barrier. But today, we were just two Americans.
Tommy: You're Canadian.
Dick: What?!
Tommy: Your passport here says you're Canadian.
Harry: Guilty.
Dick: No! How come I'm not American?
Tommy: Well, I thought it would look pretty suspicious if all four members of our family were from the same country.
Dick: I can't argue with that logic. What am I gonna do? How am I gonna tell Mary that's she's sleeping with the enemy?
