Going to Pot is the fourteenth episode of Season 7 of Three's Company, and the 142nd overall episode of the series. Written by Shelley Zellman and directed by Dave Powers, it first aired 1 February 1983 on ABC.
When Mr. Sneff, the building inspector, tells Jack he'll close down the Bistro unless Jack pays him a bribe, Jack is outraged. Janet suggests that Jack secretly tape the conversation so he'll have evidence for the police. While Janet is fiddling with the recorder, Furley comes in telling Jack he got the pot he wanted, meaning a tureen for the restaurant.
After meeting with Mr. Sneff, Jack hurries the tape to the police, who after hearing only the conversation with Furley, think they are going to break up a marijuana ring. A series of misunderstandings ensue but everything is finally straightened out when Larry arrives with the infamous "pot."
