There are people in this world who have actually complained about male nudity at the Super Bowl. As if the men playing football in tight pants weren't shocking enough, the nipples of the Red Hot Chili Peppers were deemed offensive enough to warrant numerous complaints to the Federal Communications Commission. They used to wear socks on their junk. That might have made for a better show.
Why they didn't complain about the fact that the band jumped around and played to a pre-recorded backing track is beyond me.
