"I would go to the studio by day and club by night. I did a lot of ecstasy. A lot. The chorus for Please was written after Bono kept pleading with me to get off the carpet. I spent like an hour one night just dragging myself around the floor on my knees. In my defense, that carpet felt wonderful. Really great shag. We should get that rug back."
- The Edge on Pop
