When I was a humor editor at Hallmark Cards back in the day, part of my job was to read greeting card copy and look for any possible innuendo.
Was it dirty or gross? Could people take it wrong? Especially it if was unintentional, it was my job to suss it out.
Apparently the writers of these cookbooks don’t think that way.
“Dump” to them only has the one meaning…to ‘drop heavily or suddenly,’ which appears to be their intent.
But every time the infomercial airs — and it airs a lot —
I’m afraid a very different and unappetizing meaning for ‘dump’ comes to mind.
Sorry, Cathy. I’m ordering takeout.

You nailed it. Never saw this, but in the Coleman house we’d be all over that dump cake. Thanks and peace, John
I see it all over late-night television (when I watch it on DVR in the morning). It is..disturbing. 🙂
