I've got an ear worm - even worse it's a mis heard lyric (y'know like the famous Hendrix 'scues me while I kiss this guy'

the original is (I think) 'what you don't have you don't need right now'

What's in my head is 'What you don't know you don't need to know.'

it just tumbled out of my mouth when someone at work asked me if a colleague had a 'ehem...y'know...problem'

Restraint of pen and tongue surely failed with my reply 'as the song says, what you don't know you don't need to know'

Colleagues reply 'ah, thought so'

Bugger.

lessons learnt - 'think before you speak'

'Say what you mean to say'

maybe a better response would've been 'I dunno, ask him'

Life eh? not always easy
