Ted: Mom, did you plan to have me, or was I a mistake?
Valerie/Mom: Oh, well, uh, both, really, Ted.
Ted: Mom, what do you mean? How could I be both planned and a mistake?
Valerie/Mom: Well, you see, dear, your Father and I planned to have you...
Ted: Good, I'm glad.
Valerie/Mom: ...And once we did, we realized it was the biggest mistake we'd ever made.
