"You're so vain, I bet you think this thread is about you...". Whoops, an ego is showing...

I have found that it takes and ego to recognise an ego.

I have always thought that to be a very silly song. If you write a song making a judgement about how vain you consider people of your aquantance to be - then you can hardly judge them again in the song, for thinking the song is about them.

Because the song plainly is about them.
