Six guys from the football team - 2 held onto my ankles, 2 held onto my arms, while the other 2 tied me to the halyard and hoisted me up the flagpole (I was too busy screaming to notice if anyone saluted me).
Twelve - my mother, father and 10 other unwilling stand-ins when my biological parents were preoccupied with their own selfish wants. Not one of them did any of the "hard work" you refer to. I should count myself as one of them because I did most of the work. Call it thirteen.
