9. Soy Bomb
Stage invaders are as annoying for performers as they are brilliant for fans at home.
People running on stage whilst an artist tries to do their thing are a tradition old as time and few have picked their moments better than Michael Portnoy.
Portnoy wasn't a stage invader in the traditional sense. He was actually hired as a backup dancer for Bob Dylan's performance of the song Love Sick at the 1998 Grammys. Dylan was up for some pretty major awards, including Best Album, so he needed this night to go well.
It would be a shame if, for example, one of his dancers broke away from the pack and started wiggling around behind Bobby D with his shirt off.
This is exactly what Portnoy did. As if this wasn't weird enough, the performance artist did all of this with the words "Soy Bomb" written on his chest.
What did this mean? According to the man himself, it was a poem - soy meaning life, bomb meaning explosive.
No offence, mate, but that's not a great poem. Doesn't even rhyme.
An ultimately harmless prank, the Soy Bomb moment will go down as one of the most surreal moments in the history of the Grammys.
