"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 Popmart stage design, which looked like a supermarket, appealed to Bono as a supermarket, with its myriad choices and temptations, could function as a metaphor for U2's songs, as they often deal with the struggle between desire and faith.
