My bees belong in a Skiffle Band

I caught them washboarding last night!  This is a mysterious activity they indulge in, and the best part is: no-one knows what it means, what it's for, or why they do it.  

Check out my video - at about 5min 20 seconds in, you'll see a whole lot of the girls doing it together.
