It might be:

"Ten men slept in a boarding house bed,
roll over, roll over.
They'd all roll over when anyone said
'Roll over, roll over.'
One man thought it would be a great joke
not to roll over when anyone spoke
and in the great struggle he got his neck broke
roll over, roll over."

...and, of couse, the number goes down from 10. I didn't notice if anyone else had mentioned it, so I thought I would.
