SpongeBob and Patrick are playing with the rubber bands from their newspapers. They then hear chirping and both say they didn't make the noise. They spot a baby scallop in a coral tree who was making the noise. They name him "Junior" and decide to adopt him, with SpongeBob as the Mom and Patrick as the Dad. However, the next day Patrick eats breakfast and then explains that he has to go to work as he is the dad thus leaving SpongeBob to do all the house work. He promises to give SpongeBob a break when he gets home. He eventually returns home only to be exhausted from work, and then decides to sit on the chair and watch TV for the rest of the night. This goes on for several days until SpongeBob can't take it anymore. Eventually, SpongeBob angrily lashes out at Patrick. He then shows all the diapers that junior used. Patrick then realized the error of his ways and promised to come home at 6:00 and give SpongeBob the whole night off. However, he returns at 12:00 Midnight from a party at work. SpongeBob isn't happy and follows Patrick only to find out that "work" consists of Patrick watching television under his rock. He explains that it isn't as easy at it seems; sometimes he has to move the antenna, sometimes he loses the remote, and sometimes he has an itchy butt. SpongeBob doesn't buy it and then opens up Patrick's briefcase and dumps ice cream and donuts all over Patrick.Patrick then reveals that he wasn't home by 6:00 as he decided to "work" overtime. Angered, SpongeBob yells "OVERTIME?!" Then the two begin to fight, until they see Junior jumping out a two story window. They try to catch him, but fail and begin crying for him, believing him to be no longer alive and proclaiming themselves "bad parents." However, then they realize that Junior's alive and well, and has learned to fly. After Junior kisses SpongeBob and flies away, Patrick asks "Hey! what about Daddy?" Junior drops a coconut on Patrick's head to get back at him for his laziness but still gives him a kiss, and he responds "That's my boy." After the parents say goodbye to their son, Patrick says "Let's have another," and SpongeBob makes a shocked face as the episode ends.
When SpongeBob is wearing hair rollers on his head, he has orange hair.
Normally in the show, worms are parodied as dogs, while snails are parodied as cats. Yet in this episode the worm was really a real worm. This is possibly because it is from the land, not the sea.

For some reason, when SpongeBob and Patrick are trying to save Junior from falling out the window, SpongeBob tells him to jump into his pocket.
The SpongeBob puppet in the episode blinks his eyes and looks at Patrick while actual SpongeBob doesn't.
When SpongeBob shows funny faces, you can see the side of his head before he reveals he is using a puppet.
The word "bivalve" is another name for a mollusk, an oyster, or a clam.
When Patrick realizes what's wrong, the puppet appears to be living just like SpongeBob as he made a regular face. This could be related to SpongeBob's budding as seen in "Pressure."
Patrick reveals he has worn diapers for almost a year after changing Junior for the first time, but in most of his other appearances he is shown wearing briefs. Another time he was seen wearing diapers was in "Money Talks."
In certain countries, Patrick's line "Let's have another." along with SpongeBob's shocked reaction to the quote were cut out.
SpongeBob stores used diapers in the refrigerator, the couch, and the walls. While these are all weird places to put diapers, the refrigerator is the worst, as it's never a good idea to put used diapers anywhere near food.
Instead of letting Patrick go to his "job" everyday, SpongeBob could have just made him stay home with Junior while he went to his own job at the Krusty Krab, or brought Junior with him to work. But this episode might possibly take place sometime before SpongeBob got his job at The Krusty Krab, or he could just be on vacation.
Running Gag: Patrick watching someone getting hit on the head with a coconut and keeps breaking promises with SpongeBob also, SpongeBob works on chores.

When Patrick goes back to "work" SpongeBob is in a women's night gown still, but when he got to Patrick's Rock, he was in his regular clothing. Maybe he changed his suit before going to Patrick's Rock.
When Junior was in SpongeBob's pants, SpongeBob was in his underwear. When he goes to feed him, SpongeBob's pants are back on.
Unless the motor on Gary's skateboard was connected on the wheels on the underside, then it shouldn't have been able to move.
