15. The Replacements: January 18th, 1986
The Minneapolis punk misfits manufactured a legendary feat of career suicide. After boozing it up backstage with host Harry Dean Stanton, they stumbled through "Bastards of Young," then switched clothes before coming out to attempt "Kiss Me on the Bus," during which frontman Paul Westerberg yelled "Come on, fucker" at guitarist Bob Stinson, who obliged by mooning the audience. The chaos led to the band receiving a lifetime ban from Lorne Michaels. "We were trying to do whatever possible to make sure that was a memorable evening," Westerberg said.
