It starts as a normal day at the Krusty Krab. Mr. Krabs is counting his money, but when he gets to his 456th coin, he splits his nail. He calls in for an appointment and said they had an open time now. He then flips the mustache on his grayscale picture, goes down a plank and heads to the door. When he gets to the door, SpongeBob asks him where he's going. Mr. Krabs said it was "top secret." SpongeBob then questions that Mr. Krabs has a secret. Then SpongeBob asks who is going to be in charge when he's gone.
Since Squidward is too lazy, he puts SpongeBob in charge of the Krusty Krab. SpongeBob is determined to do a great job when he is in charge. SpongeBob wakes up Squidward, who is asleep, and tells him to continue working. Squidward knows that SpongeBob is easy to fool, so he said that he is supposed to rest, and to not wake him up.
When SpongeBob asks him who is going to take orders, Squidward tells him to do it. SpongeBob knows he has to cook patties, give them to the customers, and to clean the toilets. So, Squidward lies again by pointing to Frank and said he wants to be a fry cook, and lets him cook his own patties. So, SpongeBob lets the customer cook the patties.
Then, Squidward sees SpongeBob serving the food to the customers, and Squidward says that SpongeBob's hands are filthy, but his feet are clean (In reality, it is reverse). So, SpongeBob serves the food with his feet with a customer being grossed out. Later, SpongeBob orders some decorations to make the Krusty Krab look nicer. Squidward lies once again and told SpongeBob that Mr. Krabs keeps the Krusty Krab a dump to make the food seem to taste better. So, SpongeBob covers the entire inside of the Krusty Krab with garbage and sludge. The customers start to leave, and Squidward said to bring them back, SpongeBob must provide some entertainment for them.
SpongeBob starts to dance, and the customers start to become afraid of him. Soon enough, Mr. Krabs gets back and he finds SpongeBob doing the Russian and Irish dance and the customers cowering in fear, the Krusty Krab is a filthy mess, some stranger cooking the patties and Squidward sleeping on the job (which is normal according to Mr. Krabs). SpongeBob explains he did everything Squidward told him by telling him secrets. Mr. Krabs thinks Squidward told him about his split nail. So, since SpongeBob is still in charge, Mr. Krabs has to clean dishes, and he hurts his finger again. The episode ends with SpongeBob Irish dancing to the frightened customers.
