Tiger Woods, Stanford University

OK, so he's uttered his apologies, but Woods still has enough challenges on the role model front that an invite from Palo Alto seems unlikely. Plus, the golfer, nicknamed ''Urkel'' by his Stanford teammates, didn't graduate -- he left school after two years for a career as a pro.

At least one person from Stanford speaks of Tiger fondly. Irene Folsom, who attended Stanford with Woods and said she dated him for a year and half, came to his defense.
