I swear something like 50% of those digests are totally incorrect as well. It's amazing they have kept the feature because it has never had a very high signal-to-noise ratio. I never trust what's presented in these digests without double-checking the source page.
I remember when rich snippets (one type of those widgets) came out there were a lot of funny examples. One for a common query about cancer treatments that pulled data from a dodgy holistic site saying that "carrots cured most types of cancer" (or something like that).
There was a similar one where Google emphatically claimed a US quarter was worth five cents in a pretty and large snippet graphic.
The most memorable rich snippet humor I've seen is a horse breeder sharing a story of how her searches gave snippets with my little ponies as the preview image.
