I believed for a long time that the first verse of silverchair's 'Freak' went 'No more maybes/your baby's got rabies/sitting on the floor/in the middle of the Emmys.' and this had actually happened - Daniel Johns's girlfriend had caused a commotion at some award ceremony by refusing to sit on a chair because she was crazy.
i don't know where this came from, as i knew NOTHING about Daniel Johns or his girlfriend(s).
