Plot

A friend who has taken a vow of silence creates a stir at multiple parties, Larry eats Jeff's dog's last meal, and Richard Lewis is snubbed meeting Larry for lunch.

Jeff and Susie are going away to NYC for 3 months to help Sammi settle into university. While driving in, Larry is irritated by an idiot who parked his car across 2 parking spaces. He meets Susie and Jeff's friend Vanz who has taken a vow of silence. Before leaving Larry wants to have lunch with Richard and they make plans together to meet for lunch.

At the dinner line, Larry objects to a woman doing a "Chat and cut". chatting up a person at the front of the line and then cutting in. Larry calls this woman out and embarrasses her. Larry meets Jeff's friend who is a Vet. He chats up his wife and asks her how much her husband earns, which offends her.

At the party a social worker Matt Tessler (Michael McKean), asks Larry to attend a charity event on Saturday. Larry lies that he is going to NYC, to get out of it. Actually, Larry was leaving on Sunday, but used the NYC trip as an excuse to not attend the charity event.

Next day Susie's dog Oscar is sick, and Jeff takes it to the same vet. The vet says that they will need to put him down and suggests they get him a last meal. Susie asks Larry and Jeff to go and get ice cream for Oscar. While Jeff waits in line, Larry gets into an argument with another driver who parked across 2 car spaces.

He then sees Tessler walking over and jumps into the shop to avoid him. He talks to Jeff and is accused by the other customers of doing the "Chat and cut". They force him out of the shop where Tessler confronts Larry for not being in NYC as he said. Tessler says that the event was postponed and will happen anytime over the next 6-8 weeks. Larry says that he will be in NYC for the whole duration working on another show with Jerry.

Jeff gets the ice cream, but Larry and Jeff are famished, and they finish the ice cream before they get back to the vet and tell Susie that the shop was closed. While coming back they see Vanz at a traffic stop who sees them having the ice cream. Richard fails to show up for lunch with Larry and says there was no confirmation. Larry insists that they have lunch on Sunday and their current talk is the confirmation.

At the funeral Susie is distraught and confides in Vanz how Oscar wanted an ice cream as his last meal and how the shop was closed. Because of his vow of silence, he is unable to explain to Susie that Larry and Jeff ate the ice cream. Tessler finds Larry at his office and confronts him again why he is not in NYC like he said. He then offers Larry his own apartment for stay in NYC. Larry is now committed to going to NYC and drives to tell Jeff and Susie, who are having dinner with Vanz.

Larry finds that the original car which parked across 2 spaces outside the restaurant and puts a filthy note on the windshield. Turns out the car belonged to Vanz and he breaks his vow of silence to curse at Larry and tells Susie that Larry ate Oscar's ice cream.

On Sunday, Larry is on a plane with Jeff and Susie to NYC and forgot all about his lunch with Richard, who gets stood up at the restaurant.
