fwiw, from North East Fife (Scotland), it has been ('89/'90) "the Batmobile lost a wheel, and landed in the Tay", the Tay being the big volume river between Fife (the Scottie dog shaped bit on the East) n Dundee/Tayside (with the Tay having come via Perth etc)

My wife and I had a good chuckle at these. The one we both remember is the one about Penguin losing his lollipop and buying a Milky Way.

Someone should tell the author that Robin laying an egg is the source of Batman's smell.

Does "While Shepherds Washed their Socks by Night" count?
