Friends Season 3 Episode 8 : The One With The Giant Poking Device (2)
When Chandler is about to buy Janice an expensive gift, Joey tells him that he saw Janice kissing her ex-husband. Meanwhile, Monica accidentally bumps Ben's head into a post. Phoebe is convinced that she is cursed because every time she goes to the dentist, someone around her dies, and a toothache is forcing her to make another visit. After returning, she frantically tries to figure out who must have died. Everyone is accounted for until Joey notices that the "ugly naked guy" who lives in the building across from theirs isn't moving. In an attempt to see if he's dead or just sleeping, they tape together chopsticks to make a long stick with which they poke him through his window from the balcony.
