Don't dare to throw anything on stage when you are at a Kanye West concert! A fan recently got kicked out of Kanye concert for throwing business cards onto the stage. MTV reports that the rapper, who was performing at Washington's Tacoma Dome with Jay-Z, demanded that an entire section of the audience was dismissed unless the perpetrator came forward. "I see it come from that direction, so all four of them got to go. Unless one person raises their hand and says, 'I'm the one who did it', all that whole section gotta go," he said on stage following the incident. Kanye claimed that the fan jeopardised the safety of the performers by introducing potential slip hazards to the elaborate stage setup, which included two giant platforms. "These cubes go 20 feet in the air, fam. We risking our lives up here, you can't go throwing s**t that we gonna slip on," he added. The culprit was identified and kicked from the venue. Shame.
