"Schlemiel! Schlimazel! Hasenpfeffer Incorporated!"

When Mrs. Babish's mentally slow daughter, Amy, comes to visit, a moving relationship soon develops between her and Lenny - despite the fact that almost everyone believes Lenny just wants to take advantage of ""the slow child"". But to everyone's amazement, Lenny really comes through as a thoughtful, sensitive and caring person toward Amy.
