One day at the Krusty Krab, Mr. Krabs' keen sense of smell informs him that his cash register has a deficit of one penny. As he cries over his loss, SpongeBob reassures him that losing one penny is not that big of a deal. Mr. Krabs, however, sees that money as a very big deal, considering all that it can buy, and proclaims that nothing in the world matters more. Nothing, that is, except for the beautiful visage of Mrs. Puff he suddenly spies.
SpongeBob tells him who she is and offers to introduce the two of them. Despite Mr. Krabs' pleas that he is too old for love, SpongeBob brings him over to Mrs. Puff's table. However, Mr. Krabs becomes extremely nervous and his attempts to communicate with her result in him talking in unintelligible speech as well as making strange body movements. SpongeBob steps in and after a series of mistakes, he tells Mrs. Puff that Mr. Krabs is trying to ask her out on a date. Surprisingly, she finds Mr. Krabs to have quite a way with words and accepts his offer, much to his joy.
That night, Mr. Krabs takes Mrs. Puff to a fancy restaurant and showers her with lavish services: foot rubs in between courses, caricatures, live music from a scuba diver, and transportation in a limousine. Mr. Krabs then receives a bill and is outraged that he is being charged $100. The waiter apologizes and hands him the proper bill. Upon learning that he is actually being charged $100,000, a horrified Mr. Krabs screams so loudly it causes the glass bottle that the restaurant is contained within to explode.
Back at home, Mr. Krabs sobs hysterically as SpongeBob questions him on how he could spend such a ridiculous amount of money in one night. Mr. Krabs says that in his infatuated state, he couldn't help himself. He starts to worry about how much money he'll lose on his date the following day, then gets an idea: he gives SpongeBob his wallet and tells him to come along on the date to prevent him from spending any more money.
The next day arrives, and Mr. Krabs decides the most cost-effective activity would be to take Mrs. Puff to the park. But after arriving at Mrs. Puff's house, Mr. Krabs commands SpongeBob to buy Mrs. Puff some flowers and a box of chocolates, as well as a large amount of increasingly expensive and unnecessary things. But each time SpongeBob returns with the requested purchase, Mr. Krabs gets mad and scolds him for breaking their agreement. Eventually, a tired and fed up SpongeBob calls him out on his inconsistency, to which Mr. Krabs laments that he does not want to lose Mrs. Puff, who is still waiting to go to the park as she sits upon the mountain of gifts and sobs again.
Feeling bad, SpongeBob leaves and comes back with a washing machine that Mr. Krabs supposedly asked for. But the latter once again berates SpongeBob for spending his money, and after he makes a snide comment and wonders whether Mrs. Puff will need a dryer as well, SpongeBob has got something to say.
Finally having enough, SpongeBob snaps, then badmouths off Mr. Krabs for his behavior, before angrily leaving the area. A shocked and blushing Mrs. Puff walks up to an even more shocked Mr. Krabs and calmly tells him that for her part, she does not feel comfortable accepting so many such expensive gifts, preferring to "go Dutch". She then hands Mr. Krabs some money, while calling him sweet and kisses him, leaving him utterly love-struck as the episode ends.
