In “Lucy Does a TV Commercial,” the fictional tonic Vitameatavegamin contains 23% alcohol. That unexpectedly strong ingredient is the engine of the episode’s escalating comedy.
Lucy wants to appear in Ricky’s television commercial and repeatedly rehearses the sales pitch while swallowing spoonfuls of the product. She initially dislikes its taste, but the alcohol gradually makes her intoxicated, causing her speech and behavior to unravel during the live broadcast.
The episode aired on May 5, 1952, as the 30th episode of I Love Lucy. The tonic’s name jokingly suggests a mixture of vitamins, meat, vegetables, and minerals, disguising the fact that it is also alcoholic.
A frequent source of confusion is the number 11%. The story notes that Vitameatavegamin was originally described as having 11% alcohol, but the amount used in the televised gag was raised to 23%. The prop liquid itself was not an actual alcoholic tonic.
