Video Evidence: Mariah Carey, 2001

Ice cream can be a cry for help. In her Glitter years, Mariah Carey had a bad case of crazy that landed her in the hospital, citing "emotional and physical breakdown." A week prior to her bout with exhaustion, Carey dropped by TRL unannounced with ice cream for the fans.

The normally unflappable Carson Daly was flustered by the scene, which began with Carey claiming that Carson was "her therapy," and escalated to a PG-rated striptease.

Right before a desperate cut to a commercial break, Mr. Daley said what everyone was thinking: "Mariah Carey's lost her mind."
