- Marcie, show some manners. Shake Pete's hand. Tell him you had a good time.
- Look at that, Chuck. Poor Marcie's all broke up about Pete.
- Poor kid. Too bad Pete has fallen for me.
- I couldn't give the kid a tumble, though. He'll just have to get over it.
- Pete, you're an okay guy, but we're going to have to say goodbye.
- These summer romances aren't for me. Sorry, kid. You'll just have to get over it.
- Get in the car, Marcie. Let's go! Let's go!
- Goodbye, Pierre. You've been a great help, and we appreciate it.
