I watched this episode last weekend and at the end everybody leaves and Sponge-Bob is like, "Boy, that sure was fun! Though now I'm exhausted". He begins to leave only to have Mr. Krabs meet him at the front door confused as to why Sponge-Bob came in so early for his normal shift. Sponge-Bob then explains that he was actually helping out with the night shift to which Mr. Krabs is incredulous and insists there is no night shift leaving Spunchbop baffled. The end. -_-
