Clyde comes over to have a sleepover with Lincoln, but things do not go quite as planned, when Clyde prefers to spend more time with Lincoln's sisters, than with him.
Lincoln is excited to have Clyde come over for a sleepover, especially since his father usually forbids sleepovers, due to his sisters' past efforts leading to disaster. When Clyde arrives at the house, Lincoln wants him to strictly stick to his long, detailed itinerary, including watching the 5-hour director's cut of King of the Rings. However, Clyde prefers to join in the girls' interests, and has fun with them, causing Lincoln to freak out over how much time they're wasting. Eventually, the two friends have an argument over how the sleepover should go, and they have a falling-out.
To spite Clyde, Lincoln brings over some of his schoolmates to sleep over with him but his sisters antics drive them all away. Realizing that Clyde not only tolerates his sisters, but likes them as well, Lincoln feels guilty about the way he treated him and goes over to his house to apologize. However, as he tries to, the lumps under Clyde's bed covers don't move, making Lincoln believe his friend is giving him the silent treatment.
Lincoln goes back to the house, feeling he drove away his best friend, only to discover that Clyde never actually left the house since he passed out from seeing Lori like he always does. Clyde tells Lincoln that the lumps in his bed were actually his stuffed animals and explains that with being an only child, he can get kind of lonely. The two friends make up and Lincoln tears up his itinerary. The story ends with Lincoln, Clyde and the girls gathered on the couch to watch King of the Rings together, and Clyde faints again from seeing Lori. Then Leni questions if there are peanuts in everything.
