Off work with a knee injury, Homer proves himself to be remarkably good at minding Ned's sons for him and ends up opening his own day care centre. However, whilst he is good with his young charges, he neglects his own three children. When he is up for an award for his community spirit, Lisa and Bart make sure that the film taken by a documentary crew of Homer's benevolence to be shown at the presentation includes some clips they have inserted themselves, showing him up as the bad father he is.
