Lisa: I'm safe, Daddy.
King Tut: And she'll remain safe for the paltry sum of eight million, three hundred thousand four hundred and eight-seven dollars and twelve cents. Queen's ransom.
John E. Carson: Why such an uneven amount?
King Tut: I need it to pay off the mortgage on the Pyramids. The interest rate over thirty-four hundred years is positively usurious.
King Tut: Curse you, Batman! May you fall down a flight of stairs and break every tooth in your head except one, and that way you'll have a toothache for the rest of your life, which won't be very long.
Alfred: Any results, sir?
Batman: Yes, Alfred. Just as you recall and as I suspected, Tut's apparently holding the girl in the abandoned boilerworks.
Alfred: Holy steam valve! Sorry, sir, it just slipped out. It must be because Master Robin's uppermost in my thoughts in the moment.
Lisa: Would you like to come in for a glass of milk and cookies?
Bruce: I'm afraid it's rather late. Why, it's 10:30!
