Plot

Dear Vikings: There's a new Viking-themed promotion at the Krusty Krab, so SpongeBob is determined to find out everything there is to know about Vikings. And what better way to find out about Vikings than to talk to them himself? So SpongeBob writes a letter to the Vikings, and is surprised when they decide to pay a visit to the Krusty Krab to answer his questions in person. Ditchin: Mermaidman and Barnacleboy are having a book signing, but SpongeBob can't go because he has boating school. After some convincing, Patrick finally gets SpongeBob to take a bathroom break from class-a really long one-so they can go to the signing, and SpongeBob can just go back to class when he's done! But the day turns sour when SpongeBob becomes racked with guilt about ditching class.—NAS

There is a new Viking-themed promotion at the Krusty Krab, so SpongeBob is determined to find out everything there is to know about Vikings. Since there's no better way to find out about Vikings than to communicate with them directly, SpongeBob writes a letter to the Vikings, and is surprised when they visit the Krusty Krab to answer his questions in person. However, they vandalize the Krusty Krab and kidnap SpongeBob and Squidward and take them to their ship to become crew members./Mermaid Man and Barnacle Boy are signing comic books, but SpongeBob can not go because he has boating school. Patrick then suggests that SpongeBob should trick Mrs. Puff into going to the bathroom for a long time, sneak out the window, go to get his comic book signed and go back to class. However, after getting his autograph, SpongeBob finds that getting back to boating school proves harder than he thought. The day turns sour when SpongeBob becomes racked with guilt about ditching class. SpongeBob's guilt is further strengthened when he finds out that Dale (one of Mrs. Puff's old students) turned to crime after ditching and now it is a race back to school before the day ends.
