A ten-year-old girl asked and received help from a librarian on how to use the card catalog. In a little while, the girl approached the librarian again, wanting to know how to spell "tequila."

"T-e-q-u-i-l-a," spelled the librarian, as the girl thanked her and went back to her search. A short time later she came to the desk, looking quite distraught.

"I just can't find it," she said. "What book are you looking for, honey?" the librarian asked.

Replied the little girl, "Tequila Mockingbird."
