Who's your favorite bumbling hero of all time?

James Bond and Batman do everything perfectly the first time. But sometimes, the best hero is the one who bumbles and screws everything up β€” right until he or she suddenly saves the day with a brilliant maneuver. Who's the greatest accident-prone hero ever?

Please include a picture or clip or book cover for this trouble-prone do-gooder. And please mention his or her name, and where we can find their adventures. Thanks!
