During the Superman episode Lucy promises Superman to appear at Little Ricky's birthday party. Superman was unable to come so Lucy decided to go out onto the ledge of the building and climb through the Ricardo's window acting like Superman. While outside there are many pigeons which swarm Lucy. If you look closely Lucy has a small patch of what appears to be peanut butter on the top of her helmet used to cover her curly red hair. The birds never leave her head but the truth for the annoying bird is uncovered...the annoying redhead is still a mystery :-)
