Half sheet brownies
One of the hotels I work at had a fundraiser for Charity Walk. I offered to donate something. The night before, I baked a half sheet pan (18 x 13") of brownies.
In the morning, I was talking to my friend Paul as I drove in. In answer to the common question What are you doing today? I responded, "We're having a bake sale, so I made a half sheet of brownies and I'm bringing it in now."
Which opened more than one question, apparently. Keep in mind he was at a field trip at the zoo, chaperoning three kindergartners, so he was distracted and couldn't hear me that well.
"A what?" he said.
"Bake sale," I answered.
Pause. "Are you guys doing that badly?" he asked.
"Ha ha ha. No, it's for Charity Walk," I clarified.
"What did you say you made?" he continued.
"What kind of brownies?"
"H a l f s h e e t," I enunciated over the background din of of small children.
"Oh! I thought you said hashish," he laughed.
"No! HALF SHEET," I emphasized.
Hashish brownies. Sheesh. That is an entirely different kind of bake sale.
