IGN described the scene in which Chandler and Phoebe kiss as a "gold star Friends moment." HuffPost praised it for being "gooey and romantic and slapstick-y all at once." They also called the line "They don't know we know they know we know", spoken by Phoebe, the best in the episode. The A.V. Club wrote that while it was "not the most natural point of entry for a first-time Friends viewer, given how much it leans on backstory", it was "as expertly crafted as anything in the show's 10-season run" and "builds to a frenzy, locking Phoebe and Chandler in a cruel game of chicken to see how far he and Monica will go to conceal their relationship." Various websites have deemed it one of the show's best episodes. Digital Spy ranked it the third best episode of the show, praising Perry and Kudrow's performances as a "tour de force". Radio Times named it the fourth-funniest Friends episode. GamesRadar+ regarded it as the show's fifth-best episode, as they felt it delivered "huge laughs every step of the way." They called the line "What are you doing? Get off my sister!" the best of the episode. Purple Clover chose the episode as one of the 20 funniest episodes of Friends. Den of Geek ranked it the second best episode of Friends. The episode holds a 9.7 rating on IMDb, making it the highest rated episode of the entire series, tied with "The Last One, Part 2".
