For those unfamiliar with Taxi, it should be noted herein that the cabbie's favorite hangout is a joint called Mario's. Having undergone an acute attack of "entrepreneur fever," burned-out Reverend Jim (Christopher Lloyd) has convinced himself that he could run Mario's, and to that end he buys the establishment with some of his inheritance money. Alas, though the cabbies can always be found at Mario's, no one else ever comes to the place -- except for that undercover agent from the Liquor Authority. This episode was originally slated to air on April 27, 1983. ~ All Movie Guide
