oh thank you, SyFy channel...
thanks to your (very well made) version of Alice In Wonderland, my imagination cooked this up (unlikely to be in part 2, but its fun)
Alice is telling the story to some kids (or teens), and she's gotten to a part where she and Jack have been captured, with knives to their throats.
One of the kids says "then how'd you get away?"
And Alice says, "For the Hart was a Boojum, you see."
