What earworm songs are burrowing through your head today?

[Sundae]

Europe: The Final Countdown.
I always call the hour before I finish work "the final countdown", have done for years without ever hearing the song of the same name in my head.
Even though I saw the band perform at a festival - way down on the list - while I was still sober and not sunburnt...

But Alex at work accused me of putting the song in her head, and then it became my own personal earworm. Serves me right.

It gets worse.
When I was at school, I'm your Venus by Bananarama was in the charts.
A very Bad Boy called Stewart (who talked to me because he fancied my sister) used to sing "I'm your penis" instead, which I found really shocking.
So when Europe sing "We're heading for Venus" I'm singing in my head "I'm heading for penis"... and I'm not even.
