Plot
Mr. Krabs struggles to get out of bed; after getting up, he asks Pearl if she thinks he's old, which Pearl says she does. When he arrives to the Krusty Krab, he overhears a customer complaining that their Krabby Patty tastes weird, which their mother comments that it is "all old and dried out," comparing it to Mr. Krabs, upsetting him further. After SpongeBob and Patrick announce their "big night out," Mr. Krabs asks to join, in an attempt to feel young again.
During the evening, SpongeBob and Patrick arrive at Mr. Krabs' house, and the three characters take off to a laundromat, where SpongeBob and Patrick watch their faces spin in the mirror's reflection of a washing machine; Mr. Krabs finds this activity boring, and would rather see more of the nightlife. They then partake in several more bizarre activities, none of which satisfies Mr. Krabs. At an arcade, SpongeBob, Patrick and several children ask Mr. Krabs if he's "feeling it" multiple times, which angers him, berating the duo. As he's about to cancel his night out, Patrick then changes his mind when he reveals that they are going out on a "panty raid," grabbing the interest of Mr. Krabs.
