Friends Season 3 Episode 18: The One with the Hypnosis Tape

Monica receives a tip from an admirer worth a small fortune then goes out with the guy. A hypnosis tape intended to assist Chandler to stop smoking has a rather strange side effect. Phoebe is upset when her 18-year-old half-brother, Frank Jr., makes a surprise announcement that he is getting married - to a woman more than twice his age.
