Season 4: Episode 75: The One With The Cat
Monica runs into Chip Matthews, Rachel's prom date and the popular boy in high school. When he calls to ask Monica out, Rachel thinks he's calling for her and makes a fool of herself in front of Ross. Unfortunately, Chip hasn't changed much since high school - while he's still cute, he also still happens to live with his parents and work at the local movie theater. Nonetheless, Monica fulfilled her dream of dating Chip ... and dumping Chip. Meanwhile, Joey and Chandler place an ad in the paper to sell their entertainment center. When a prospective buyer asks Joey to demonstrate the spaciousness of the unit, Joey finds himself locked away while the apartment gets robbed. Phoebe finds a stray cat and is convinced that it's her mother reincarnated. A poster depicting the missing cat is found, but no one has the heart to tell Phoebe ... except for Ross.
