What would you do if the person sitting next to you on a plane suddenly turned to you, laughing, and said, "Frozen Poop ... What will they think of next?!?" Such was my quandary yesterday aboard United Flight #856 to Washington, D.C., as the woman sitting next to me tried to engage me in a discussion about -- you guessed it -- Frozen Poop. Sensing my confusion, she called my attention to page 147 of the Sky Mall Catalogue where they're actually selling something called POOP-FREEZE, an "emergency pet product that every pet owner should have." The concept is simple: Just point a 10-ounce can of Poop Freeze at Fido's Feces, press the trigger and, voila, a quick burst of liquefied gas flash freezes the poop-in-question to minus 62 degrees, instantly hardening it for easy pickup and disposal. "Just Frost and Toss," say the good people at Poop Freeze, Inc., "It's that simple!" By the time we landed, I was a convert. I don't have a dog, but a little Poop Freeze might go a long way here in Washington where, Lord knows, there's plenty of shit flying around ...!
