Stung by the spelling bee!

The Caesar Chavez Middle School Spelling Bee was drawing to a close. Twenty-three kids had left the stage, and it was down to Shirley and Humberto.
Once again, a blue card was drawn from the deck on the podium.
“The word is insomnia,” said the judge. “Insomnia”
Shirley took a deep breath and closed her eyes. “Insomnia,” she shouted. “I-N-S…”
“INS??????”
The auditorium burst into chaos. Half the audience raced to the exits. The other half drew guns and shouted various curses in Spanish.
The Spelling Bee judge sighed. “I hate holding these things in San Diego.”
Eventually, Humberto won.
