As reported by a fellow fan:
"Reading an interview with Matt Groening today (UK "night and day" Sundaymagazine), the script for the 200th Simpsons episode includes U2 playing agig in Springfield. Apparently some gentle ribbing is planned too – at onepoint Bono launches into an eco-rant while Edge and Larry look skywards andslope off for a pint. Sounds pretty realistic to me ."
