I once saw an excerpt of what looked like a mainstream sitcom (kind of 'Friends' and such), revolving mostly in a living room in which some woman had hypnotized a guy that was friends with the people in the sitcom. She could put him easily on a trance.
The other friends asked her to remove the trigger/to stop hypnotizing him. At the end only the woman, the man that was under her spell and the best friends are in a room and she exerts her hypnotic power again towards (I don't remember well) either the guy that had been hypnotized or to the other friend...
Any pointers to which sitcom/episode/link that could refer to?
