The episode starts with Ross and Joey asking to borrow Monica's Porsche, so an angry Rachel demands to know why Monica doesn't let her drive. Phoebe reveals that Rachel thinks that Monica talks too much about the wedding, so Monica replies by letting Rachel know that she is a terrible driver.
Ross arrives at Central Perk and comments to Rachel about how fast the "bad boy" is. Rachel requests the keys of the Porsche, but Ross refuses. He then he goes to the bathroom to comb his hair (using the comb on the floor of the bathroom), and during his absence Rachel steals the keys and 20 bucks, which she claims to a nearby woman is her alimony.
Monica then asks Chandler about why his father hasn't answered the wedding invitation and Chandler reveals that the reason is because he wasn't invited. Monica claims that he would regret not having his father at his own wedding and also that she wants to get to know her future father-in-law. Chandler protests, telling her that his father embarrassed him a lot as a kid, including when he came to every single one of his swim practices and cheered him on dressed as a different Hollywood starlet, Monica tells him that at least he showed up to every single one and cheered for him. She then packs their bags and tells them they are going to Las Vegas to meet his father.
Joey decides to bond with Jake, Phoebe's new boyfriend, so he invites him to the Knicks game, but as Jake reaches down for his agenda, Joey sees he is wearing women's underwear. He tells Phoebe about this, she explains that they were goofing around and that they traded underwear. She then tells him that he is unsure about his manhood, as opposed to Jake who is so secure in his manhood that he agreed on a dare to wear women's underwear.
Rachel is "Porsche-ing" (speeding) around much to Ross's annoyance, but they are pulled over by Officer Hanson (who Rachel calls Officer Handsome), for speeding - he also discovers that Rachel does not have a valid driving license. Rachel flirts with him so he won't give her the ticket and she succeeds, after which Ross begins to drive.
Chandler and Monica arrive to the show of Helena Handbasket, who Chandler reveals to be his father. She begins to talk to the people in the crowd, and Chandler says he can't deal with his. This draws Helena's attention to him, and Chandler's father is surprised to recognize his son. Helena then notices Monica's ring, and Chandler admits they are engaged. Rather awkwardly, Helena turns to another man and says "So, you're bald." Chandler interrupts and invites his father to the wedding, and his father tells him that he wouldn't miss it for the world.
Joey arrives at Central Perk and shows Phoebe that he stole and is currently wearing Rachel's underwear. She replies by agreeing that he is a man, but is also a bit slutty. Joey relishes the feel of silk and also goes into a discussion about how pantyhose feels, but the awkward and uncomfortable look Phoebe gives him lets him know that he went too far. Joey goes to take the underwear off and comes back, telling Phoebe that after this whole ordeal he really needs to be with a woman. He goes to hit on the hot girl sitting behind them, and after telling her he was on Days of our Lives, attempts to pay her bill of $4.50, but when pulling out his wallet, he also pulls out Rachel's underwear.
Ross is pulled over, this time by Officer Petty (who Ross calls Officer Pretty), so he tries to do the same thing as Rachel but fails, and he is given a ticket for driving too slow. He is then ashamed of his attempt to be feminine and get out of a ticket, with Rachel admonishing him and telling him he has a son.
