More sensitive than usual -- if such a thing is possible -- Lucy (Lucille Ball) becomes convinced that everyone has forgotten her birthday. Wandering disconsolately into Central Park, lonely Lucy is "adopted" by a lachrymose benevolent group called The Friends of the Friendless. With her new comrades in tow, Lucy angrily storms into the Tropicana to tell Ricky (Desi Arnaz) off for his negligence -- only to get the surprise of her life (which, by her count, has lasted a mere 29 years!). This is the one and only episode in which Desi Arnaz sings the I Love Lucy theme song, with special lyrics written for the occasion by Harold Adamson. ~ Rovi
