"The One With The Cuffs" is the third episode of the fourth season of Friends, which aired on October 9, 1997.
Things at Chandler and Joey's aren't really going well, as all they've managed to obtain since the robbery is a set of rusty patio furniture, which don't really compliment the canoe. Chandler finds some solace in Rachel's boss Joanna, with whom he sleeps. Rachel is not too thrilled about this, especially since he previously agreed to set it up and then broke up with her. Rachel fears that this relationship can get too complicated without ending with serious consequences which could jeopardize her job position, so she demands Chandler to break it up. This falls on deaf ears, however, and Chandler and Joanna end up making out in her office. Joanna is suddenly called into a meeting with her boss, which she leaves for, leaving Chandler half-naked and locked in her office, handcuffed to her office chair. This Chandler does not appreciate at all, especially when Rachel and Sophie end up unlocking the door and walking in on him. He asks Rachel for help in escaping the office. Rachel doesn't agree to this as in doing so, Joanna will know that she has total access to her office. Chandler agrees to remain locked when Rachel promises him to pass on a rumor that will make him a male legend with the ladies (a promise which lasts two hours, when Joey blows the rumor off).
In desperate need of money, Monica agrees to cater a party her mother's having, with Phoebe's help. When she asks for the reason of such employment, her mother indirectly reveals that she thinks that Monica is good at her job. Unfortunately, Monica contradicts her mother some time later, when she drops a fingernail in one of the quiches she prepared. This turns out to be pretty bad, not only because of the cuisine fiasco but also because the occurrence of it spurs Monica's mother in pulling out lasagnas from the freezer and revealing to Monica that she had a bet with her father that she'd screw up. Monica is deeply depressed by this and walks out of the kitchen. Phoebe finds her in her old bedroom, which is now a gym, and encourages her not to lose self-faith and prepare something else herself instead of serving the lasagnas. This Monica does, preparing casserole and keeping the lasagnas unserved. Much to her pleasure, her mother is impressed by this and pleads guilty to the crime of not believing in her daughter.
Busy with the tedious job of removing gum from the patio furniture, Joey is interrupted in the middle of the day by a door-to-door encyclopedia salesman. Joey, who has never shown much interest in books, is yearning for knowledge that brings him on par with his friends' difficult subjects, so he lets the salesman in. A few basic questions asked by the salesman is all that is needed to show that Joey is not smart, which is the critical point the salesman uses to sell the encyclopedia to Joey, who starts really digging in the V volume. When the salesman reveals the price of the entire set to be $1200, Joey laughs in his face, thinking he's stupid for believing that an unemployed man with only patio furniture at home has that kind of money. When he starts showing his possessions to the salesman, however, Joey finds a $50 note in his pocket, enough to buy him a book. He sticks with the V volume, but when he starts to pursue subjects containing words starting with V, such as the Vietnam war, the friends find it hard to play along and change the subject to the Korean war, about which Joey knows absolutely nothing.
