After Frankie Avalon brings Kim on stage during his act, Lucy tries to convinc6e him to join Kim in a talent competition.
One of the best of Season 6, mostly a showcase for Avalon and his act but it is very entertaining. He shows off his talent for impressions, doing John Wayne, Bela Lugosi and James Cagney. Lucy figures he can do an impression of Sonny to Kim's Cher. Lucy isn't given much to do in this episode, just one sequence when she begs Frankie to do the act.
They are both very good as the duo, singing I Got You Babe and trading insults like the actual couple. The emcee for the talent show is Jerry Fogel, who was in The Mothers In Law, produced by Lucy's ex Desi Arnaz.
