5x16 "The One with the Cop"

Phoebe finds a police badge at the coffeehouse and has fun pretending she's a cop – until she pulls it on the owner, a cop named Gary, who later successfully asks her out for dinner. Ross buys a new couch, but refuses to pay the huge delivery fee. As a result, he and Rachel struggle to lift it up to his apartment and Ross soon wishes he'd just paid the money. Joey thinks he is in love with Monica, after having a romantic dream about her. However, Monica later reasons with him that this is not the case, and that Joey actually wants a serious relationship, similar to Monica and Chandlers'.
