Doesn't really matter what they are saying,
Cause I'm in love with the enemy.
Doesn't really matter what day of the week,
What matters to me is you're ready ready ready for me

The story:

I was at a karaoke club for my friend's birthday, and it was my turn to sing. I chose that song because it was one of the few songs that wouldn't be too embarrassing to sing. I wasn't paying attention to the monitor with the words on it, because I thought I knew the words off by heart. I sang them wrong, (and very loudly) and everyone started to laugh. I am, of course, blonde, so the blonde jokes about having the words right in front of me and still singing them the wrong way never ended.
