Gretchen: Francis, have you seen Otto?
Francis: What's the matter?
Gretchen: I don't like letting him out of my sight. He's been so accident-prone. In the past few days, he smashed up both our cars. He keeps falling down the stairs. This morning, he set his hair on fire with his reading glasses.
Otto: [enters] Gretchen, my love, I wonder if you can fetch the tweezers. I seem to have an ass-full of cactus.
Gretchen: Otto, it was just beginning to heal.
Otto: Well, I'm sorry. It's not like I'm doing this on purpose.
