There was a thing, for a little while, when some people thought a journalist had made a hilarious typo and referred to Sherlock actor Benedict Cumberbatch as Bandersnatch Cummerbund:
Language Log notes the 'typo' and clears it up for us that it is, very obviously, a joke. Benedict Cumberbatch is a funny name, you see, and sometimes hard to remember, so she humorously misremembered it on purpose. (Bandersnatch is the frumious creature from the Jabberwocky, and a cummerbund is an item of men's dress wear.)
But look! She spelt cummerbund right! That's more than most people on the internet can manage. Before long, one or both of those variants is going to become accepted as an alternative spelling. And of course that's fine with me.
