Tricksy Hobbits

Red: Mom, what does eleventy mean?
Me: Are you reading Fellowship of the Ring?
Red: *smug grin* (I told her it was above her reading level, which she took to be a challenge)
Me: It means Bilbo is 111 years old, but they just like that word. Kind of like Boop.
Red: Yeah, her favorite number is eighteen eleventy and a half.
Me: Maybe she's part hobbit.
Red: The only question is which side did she get it from.
Me: Your dad's - he's the one with the hairy feet.
