Talk about a ballsy move. In October 1992 Irish singer Sinead O'Connor was pissed off about child abuse scandals within the Catholic Church, so she decided to use her platform on Saturday Night Live to make a point. Without telling producers in advance, she tore a photo of the Pope in half after a performance of Bob Marley's "War." This is long before the public was aware of the Catholic Church's role in covering up child abuse, and the incident ignited a firestorm. To this day O'Connor says that she has no regrets, but it definitely dealt a near-lethal blow to her career.
