Uncle Grandpa approaches the hot dog cart and asks for a hot dog, but the vendor says that Ham Sandwich has cleared out his inventory and he's expecting a delivery later that day. Uncle Grandpa says he'll wait and a hot dog tied to a string appears in front of him and when he bites the hot dog, it takes him to the basement of some weird guy. The guy in excited that Uncle Grandpa is there and introduces himself as Nubert Nimbo and as Uncle Grandpa's #1 fan. He made an exact replica of the RV to the very last detail so he and Uncle Grandpa can live together and have Uncle Grandpa Fun Time all day long just like in his show, Uncle Grandpa questions that he has a show and Nubert shows him that he's DVR'd every single episode of the Uncle Grandpa show. Uncle Grandpa says that he has to go and Nubert gets sad, once Uncle Grandpa opened the door to get upstairs Nubert's mom convinces Uncle Grandpa stay.
Nubert wants to show Uncle Grandpa all of his stuff, first they head to a cabinet where he keeps the whole thing filled with discontinued Uncle Grandpa cereal, then he shows him the room which he calls the Creative Room of Casa de Nimbo where he posts Uncle Grandpa fan fictions and the art it inspired. Nubert saved the best for last, a room with a ton of Uncle Grandpa collectables such as a stress doll from deepest darkest Germany. The two are back in the basement RV and Nubert is excited to spend quality time with Uncle Grandpa, Nubert puts Uncle Grandpa on the couch and he'll be back for a special surprise, Belly Bag is concerned about Nubert then he comes back dressed as Mr. Gus with a slice of Pizza on a stick and a realistic cat tied up. Uncle Grandpa tells Nubert that Uncle Grandpa Fun Time has a way of sneaking up on you and he tells Nubert to get more hot dogs.
4 weeks had passed and Nubert looks defeated waiting for Uncle Grandpa to get out of the bathroom, Uncle Grandpa then walks out all pruned up telling Nubert that he used all the hot water. Nubert supposes that he won't be taking another bath that week and he goes to his creative room to see all the portraits of Uncle Grandpa defaced with heads of horses, Nubert is still happy that Uncle Grandpa defaced them though. He walks past the bathroom to see Uncle Grandpa put all the recalled cereal in the toilet, and Uncle Grandpa says he has to do it to feed the toilet monster before he does his duty. Nubert then goes back to the basement RV to watch the Uncle Grandpa episodes on the DVR but he finds out that his 15 years of work had been deleted by Uncle Grandpa for his shows. Nubert then goes to his private collectables room to see that Uncle Grandpa is melting all the toys to make a molding of Nubert's favorite character, his mother. Newbert is over Uncle Grandpa and proceeds to go out side which worries his mother because he's never been outside before, Nubert is putting on some roller-blades to leave and Uncle Grandpa is trying to convince Nubert to go back inside, Nubert rolls down the drive way in terror and Nubert's Mom demands Uncle Grandpa to save him. Uncle Gradpa puts on some ice blades and chases after Nubert and Uncle Grandpa reaches Nubert before he falls in the street until some toast knocks Nubert down into the street causing him to get run over by a truck.
Uncle Grandpa visits Nubert at the hospital, and his mother says he'll be alright in about 6 months, 2 years tops. Uncle Grandpa says he only stopped by to apologize for any inconveniences he may have caused him and to give Nubert a photo signed by him. After Uncle Grandpa staples the poster onto Nubert's arm, Nubert now realizes that there's more to life than the Uncle Grandpa Show after he had gotten out of the house, and the world has something more to offer and she's on the TV right now, then Nubert chews the photo and spits it at the TV to turn it on to Xarna.
