After Marge baby-sits for Ned Flanders, his sons Rod and Tod request more of her company as she encourages them to do all the risky things from which Ned has tried to protect them, such as scaling an adventure climbing wall. When Bart is grabbed by a chimpanzee as a surrogate son and taken to the top of the church steeple, Rod's new-found interest in climbing saves the day as he carries the chimp's real son, Mr. Teeny, to the top of the tower to exchange for Bart.
