Jingle bells, Batman smells/Robin flew away/uncle Billy lost his willy/on the motorway...
(sung to the tune of the Xmas song)
it's one of a handful of rude rhymes my children learned early on in primary school. This was in the Southeast in the 2010s, but a friend who grew up in Manchester in the 1970s said he knew this rhyme too.
I'd just like to get a sense of how widespread and how old it is. Has it been around since the first Batman TV series of the late 50s (I think)? And do you have other examples of disrespectful children's rhymes featuring pop cultural references? Or rude rhymes full stop? I find this one oddly joyful....
