Oh, it’s Girl Scout cookie time. I keep passing packs of little girls standing outside the supermarkets, eyeing me with predatory smiles as they size up my buying potential. Sorry, girls, I try to telegraph back in a friendly yet no-sucka-here look. I’ve already placed my order.

This weekend, I’ve mentioned to a number of friends that there’s a box of Thin Mints out there with my name on it. Over and over, the response has been: “I love Thin Mints when they’re frozen!” What’s the origin of the frozen Thin Mint thing? The Girl Scout online history museum says that Thin Mints have been around for more than a half-century, but I can’t find any info online about when we all started freezing them. Do any of you former Girl Scouts remember a specific campaign — say, in the 1970s or early 1980s — when your troop leader urged you to sell your marks extra boxes so they could store the cookies through the summer? I remember sneaking out to the garage to open up the deep-freezer and pluck out a couple of Thin Mints, and it seems like everyone I know in their 30s shares the same memory.
