|Upside down goose with right-side up head.- Dailymail.UK|
The Dailymail.UK had this posting about a technique called "whiffling"
that geese use to slow down for landing in a high wind. The picture above shows an upside-down goose with its head turned 180 degrees. If you still don't get it, (I had a hard time at first) check out this video. This turns the phrase "dumb as a goose" on its head, so to speak.
