Do you ever get a phrase that repeats in your head over and over again all day?

[Buckets]

I can't be the only one . Today's mantra (from the side of a bottle of bath oil) is Reckitt Benkiser.

i have been singing "supermassive blackhole" all day

The whole song or just the title? If it's a song caught in your head that's called an earworm I believe. Can you hit the high notes?

Oh this is so annoying, it happens to me loads and quite often at night when i am trying to get to sleep. My latest one was Ptang Yang Kipperbang which I think is a book I read at school.

i don't know the whole song so its mostly just wang doodle WAAAANg do doobie glaciers melting in the dead of night Mm mmmmmmm Supermassive blackhole!
