Jerry and Elaine travel to Florida for a dinner in honor of his father. Jerry gets into an argument with a neighbor of his parents over an "astronaut pen."

Jerry and Elaine visit his parents in Florida and to attend a dinner in honor of his father. They meet the neighbors, Jack and Doris, and after Jerry admires Jack's astronaut pen, he offers it to him, which Jerry gladly accepts. He didn't really want to give it to him which leads to non-stop gossip. It all leads to an interesting dinner. Elaine meanwhile has an uncomfortable night on the pull-out bed - the lack of air conditioning doesn't help - hurting her back. Desperate to go back to New York, she is told by a chiropractor she has to stay for another 5 days.—garykmcd

Jerry and Elaine go to Florida to visit Jerry's parents for the weekend and plan on going scuba diving, which Helen (Liz Sheridan) doesn't see the point in doing. Morty Seinfeld (Barney Martin), Jerry's father, is also being honored at a ceremony the next night. He is the outgoing President of the condo association. Helen wants Jerry to make a speech and do one of his comic routines. Helen wants to know the situation between Jerry and Elaine. Jerry explains that he and Elaine decided that they could not be friends if they were sleeping together. So, they are not a couple now.

Jack Klompus (Sandy Baron) and his wife Doris (Annie Korzen) come over to write Morty a check for a previous night's dinner and Jerry notices Jack's pen. When Jerry asks Jack about it, Jack tells him that it can write upside down and that astronauts use it in space. Jack offers an interested Jerry the pen. Jerry refuses his offer several times, but Jack persists, and Jerry finally gives in. Helen Seinfeld, Jerry's mother, asks why he took the pen and says he should give it back because Doris will tell everyone in the condo that Jerry made Jack give it to him. Helen says that Jack loves that pen and talks about it all the time. Jack only offered it as he never thought Jerry would accept.

That night, Elaine sleeps on a sofa bed with a bar that sticks up through the mattress and hurts her back, making her extremely uncomfortable, while not being helped by the fact that the air conditioning is turned off, since Jerry's parents are "nuts about temperature". Jerry tries to comfort her by saying they only have two more days left before they go back to New York. The next morning, Elaine's back is so sore that she cannot go scuba diving with Jerry, so he goes without her. Morty suggests she take muscle relaxants to ease the pain.

Just as Helen predicted, rumors begin to spread around the community that Jerry wanted Jack to give him the pen. When Jerry returns, he has black eyes because the capillaries around his eyes burst when he went underwater, and the pressure was too tight on his mask.

Jack comes over again, and Jerry returns the pen. Morty berates Jack for "taking Jerry's pen". Elaine decides she wants to take the muscle relaxants but takes a slight overdose and acts goofy at the ceremony. The ceremony has been organized by the condo community to see off Morty as he retires from the Presidency of the condo association. Jerry has to wear sunglasses because of his black eyes.

Jack is the MC and turns the dinner into a "roast", making cracks about Morty at the podium. Morty starts arguing with Jack again about taking back the pen and they start fighting, breaking Jack's dental plate in the process, prompting a bitter Jack to sue Morty. The next day, a chiropractor looks at Elaine's back and tells her she should not go anywhere for at least five days, extending both her and Jerry's stay even longer, much to their discomfort.
