"Our house in the weekends is just one big party. We play music, people stay over. It's more like a train station than perhaps Ali would like it, but there's a lot of laughter in the house."
- 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".
