Athletically challenged misfits Clark (Jon Heder), Gus (Rob Schneider) and Richie (David Spade) learn it's never too late for glory in this goofy sports comedy that proves every (under)dog has its day -- even though it might take, say, 20 years. Humiliated as children on the baseball field, the now-adult trio forms a three-man team to take on the top Little League squads, becoming unlikely champions for uncoordinated kids everywhere.
