I was pretty good about not missing school until senior year, because senior year's basically a waste of time. I only missed seven days from kindergarten to junior year of HS. Four of the seven days were the first four days of 1st grade when I was just getting over the chicken pox....
However, if I ranked these by the likelihood of them getting broken, I'd rank them like in the following order:
Hershiser
Gagne
DiMaggio
Ripken
