"I don't believe in luck. I walk under ladders. I'd have 13 tattooed on my arse without any problem. But I do think the universe can turn cold and nasty. I'm never surprised when the worlds get a bit ugly. I'm never surprised when U2 meets resistance".
- Bono, 2015
U2 never used the word "baby" in a song before the album Achtung Baby was released. It was used 27 times on that album.
