Friends Season 10 Episode 4 : The One with the Cake
Ross and Rachel throw a birthday party for Emma and desperately want everyone to be there for it. Everyone has prior commitments: Chandler and Monica have a romantic weekend planned, Phoebe has a client, and Joey has an audition. Ross's parents show up and the group begins celebrating. Rachel soon realizes the cake is not a bunny, as planned, but an erotic image with her daughter's picture on it. She goes off to get it fixed but Ross needs to go get her. Phoebe, Joey, Chandler and Monica battle to see who can leave with Monica and Chandler being left behind. Luckily everyone gets back before Rachel and Ross and Emma's birthday is celebrated just as Rachel envisioned.
