"You only know you have a heart when it's broken. When you are a singer in a band you stick your neck out for a living, you get used to knocks. And I've noticed that the spleen and ire of your enemy usually take them out, not you, so you don't have to do anything, almost. There is nothing more attractive than energy moving forward. Our band has it, our movement has it.. It's exciting to be on that train."
- Bono, 2009

The lyric "3:33 when the numbers fell off the clock face" from Unknown Caller is a reference to the Bible verse Jeremiah 33:3. Bono refers to it as "God's phone number".
