Jimmy Doyle is one of the jocks from high school who called himself one of the "Cool Guys" (they arent really that cool). His son, Tommy, is a spoiled annoying brat. This is partly due to how annoying Jimmy was in school. He grew up rich. During the reunion, he, along with Brad and Adriano, gave Charlie , Mac , and Frank wedgies. Jimmy abandoned Stacy and Tommy. He is a huge jerk.
