Guy: "What are you writing?"
Girl: "A paper for history."
Guy: "About what?"
Girl: "If I took one event in history and erased it, what I think the outcome would be. We're kind of limited to negatives though, like erasing Hitler, Stalin, or Idi Amin. Stuff like that."
Guy: "How about just erasing their parents?"
