Just an idea!!!

[Rick and Roll]

None - they've all either choked on their own puke or spontaneously combusted!

However, it depends on the drummer:

Neil Peart would have to do it scientifically.
Nick Mason would stare at it.
Mickey Hart would smoke it.
Bill Bruford would study the problem for awhile.
Alan White would watch Bill.
John Bonham would beat the hell out of it.
Stewart Copland would fight over it.
Simon Phillips would share it.
