Madonna - 2001 in Washington, DC. Not only was she about 2 hours late coming to the stage (claiming bad weather when it was sunny blue skys outside), but she talked throughout in that ridiculous fake British accent and didn't play any of her hit songs -- just played the songs that were never released before. To top that off, she lipsynched throughout and got caught when she was dancing and her headset microphone went flying off and she kept on singing perfect through the speakers(man did she get booed and people all around were screaming Milli-Vannilli)..

Total waste of the $95.00 ticket and will never see her again in concert.
