JEOPARDY: A few readers have called us up to see how we are at Jeopardy.

The category was “For naught.”

Here’s the answer: “This brand name of lighters that uses a flame logo can mean zero in slang.”

We knew the question: “What is Zippo?”

It’s always exciting when the Bradford company is recognized, but perhaps we shouldn’t be surprised. After all, Zippo lighters are known throughout the world for their distinctive shape, click, windproof flame and lifetime guarantee.

From Zippo’s website: “There are many Zippo collectors around the world. Their fervor and dedication to the brand is unparalleled. To enhance the collecting experience, Zippo collector clubs around the world hold meet ups and other events throughout the year.

Companies around the world continue to use Zippo lighters as an advertising and promotional tool. These ‘advertiser’ lighters continue to be among collectors’ favorites.

“Perhaps one of the biggest influences on collecting is Zippo’s ties to popular culture, Hollywood, Broadway, and the music industry. The Zippo lighter has been featured in more than 2,000 movies, stage plays and television shows over the years. Zippo lighters have “starred” in such diverse productions as “I Love Lucy” “The X-Men” and “Hairspray – the Musical.” Often the lighter is a key prop, used as a device to move the plot forward or to reflect the personality of a character or time period being depicted. The famous Zippo “click” sound has been sampled on songs, and the lighters themselves have been featured on album covers, tattooed on rockers’ skin, and wielded in Rolling Stone photo shoots.”
