5x21 "The One with the Ball"

Phoebe learns that Gary is planning to ask her to move in with him and freaks out. She asks Chandler, as a commitment-phobe, to put him off however he can't bring himself to do it after seeing the depth of Gary's feelings. Phoebe ends up warming to the idea and agrees to move in, however the relationship ends on their first morning together when Gary shoots a bird tweeting outside the bedroom window. Rachel buys a hairless Sphynx cat for $1,000 but quickly regrets her purchase when all her friends make fun of it and the cat itself doesn't like her. She eventually unloads the creature on Gunther, making a profit. Ross and Joey pass time by tossing a ball back and forth, and subsequently try to make a record of how long they can throw it, without dropping the ball. Their game is disrupted, however, when Monica feels the need to include herself. Chandler is called a 'Dropper' when he wants to join the game.
