Season 4: Episode 76: The One With The Cuffs
Chandler runs into Rachel's boss Joanna and the two end up having quite a fling. When Rachel sneaks into Joanna's office to scope out the bonus list, Chandler just happens to be handcuffed naked to a chair. Chandler, completely humiliated, begs Rachel to free him. But, after doing so, Rachel realizes that she has tote-handcuff Chandler or else her boss will know she has a key to her office. She's no better off after handcuffing Chandler to the filing cabinet. Finally, after Chandler threatens to bust Rachel, she sets him free, but under the condition that she tell Monica and Phoebe that he's well endowed. Thanks to Joey's big mouth, Chandler's exalted reputation lasts all of five minutes. Meanwhile, Monica "pulls a Monica" when she caters a party for her mother and accidentally loses a fake nail in one of the quiches. A salesman tries to sell Joey a set of encyclopedias, but Joey can only afford to buy the "V" volume. The boys furnish their apartment with a canoe and some patio furniture.
