I Love Lucy: Lucy Does a TV Commercial (1952)

One of the funniest I Love Lucy half-hours ever filmed, this is the episode in which stagestruck Lucy (Lucille Ball) becomes a commercial spokeswoman on a major live TV program emceed by Ricky (Desi Arnaz). Lucy is hired to promote a liquid medicinal tonic called Vitameatavegamin, requiring her to not only extoll the product's praises but also sample a tablespoonful on-camera. Unfortunately, the ad copy for Vitameatavegamin is so long-winded and complicated that Lucy must rehearse her pitch over and over again, and drink sample after sample of the product. Even more unfortunately (and more hilariously), Vitameatavegamin contains 23-percent alcohol. ~ Rovi
