"That song 'MoFo' is hardcore. If I could put my whole life into one song, it'd be something close to that. It's a funny thing to be able to say - that a song sums you up - cause maybe that means you're not that interesting after all."
- Bono in 1997
The title of the song '11 O'Clock Tick Tock' refers to a meeting Bono should have had with a friend but missed. The friend put up a note saying 11 O'Clock Tick Tock.
