Popular professional hypnotist Pat Collins appears in this episode, in which Lucy (Lucille Ball) seeks out a cure for Mr. Mooney's insomnia. In the course of Collins' nightclub act, a hypnotized Lucy and Mooney (Gale Gordon) impersonate Laurel and Hardy, and Lucy does impressions of Jackie Gleason and Carol Channing. Eventually, Collins comes up with a post-hypnotic suggestion that will enable Mooney to catch a little shut-eye--and which, of course, Lucy will inadvertently trigger at all the wrong moments! ~ Hal Erickson, Rovi
