Well done, bov.
Bellambi is correct. Bambi is the deer, and she has swallowed a historic measure called an ell. The ell was also called a cubit - about the distance on a man's arm from the tip of the middle finger to the elbow. ( You may now include that in your book of "101 Totally Useless Pieces of Information." ).
Now bov is back in the quizmaster's chair.
