The story begins with Beavis and Butthead watching a pornographic film. Beavis states that he wishes those chicks were real. Suddenly, the duo hear a knock on the door, and Butthead answers it, and sees what appears to be a chick, and he calls Beavis to check it out. After a few seconds, Uncle Grandpa's head appears and says "Good Morning". Afterward, Uncle Grandpa appears from behind the show, saying that was a good show. When Butthead asks who he is, he says "I'm your Uncle Grandpa". The big headed duo think that means he had incest with their parents, and Belly Bag explains that he's not just their Uncle Grandpa, he's everyone in the world's Uncle Grandpa, "and when he comes to visit, you're sure to have a fun time". Beavis thinks Uncle Grandpa must get all the chicks. Uncle Grandpa states he had a chicken coop at one time, then, he goes on to say that he hears that Beavis and Butthead have a hard time trying to score. Butthead says that's correct. Uncle Grandpa says he knows how to handle that, and asks Belly Bag for a door. Belly Bag complies, and the three enter the door. Later, Uncle Grandpa is seen driving the UGRV, and pulls Beavis and Butthead out of the glove compartment, and tells them they're in the UGRV. Another Uncle Grandpa arrives and gives the duo a tour of the RV. In the RV, they meet Pizza Steve, whom they try to eat, before being stopped by Belly Bag, who says they have more important matters ahead. Uncle Grandpa takes them to the kitchen, where they meet Mr. Gus, whom Uncle Grandpa asks for the "UG Enchantment Enhancer". Mr. Gus gets it, and Beavis and Butthead express desire to finally score, but Belly Bag says they should read the instructions first. Butthead reads in this traditional "words, uh, words, uh, words, uh, words, uh" phrase. Afterward, the duo take turns putting it on themselves, then Uncle Grandpa takes them to the mall to test it out. There, the duo attract the attention of two red haired chicks, whom the duo ask if they want to "do it". The girls are eccstatic about it, but ask to meet them again in two weeks. The duo are happy that it worked, but are upset that they have to wait two weeks, so they apply more of the Enchantment Enhancer, and gain the attention of a whole crowd, then apply more, and gain the attention of everybody in the mall, and everybody chants "BEAVIS, BUTTHEAD". Right about then, Principal MicVicker enters the mall and is surprised that Beavis and Butthead are popular, calling them morons. This upsets the crowd, who call him a "blasphemer" and attack and kill him. Belly Bag says they put too much of the Enchantment Enhancer on them, and have reached "Deity Status". The duo apply more of the Enchantment Enhancer, and become popular worldwide. Even everybody at school begins to admire them, minus Daria, whom everybody calls a "blasphemer" and chases out of the school. She meets Uncle Grandpa, who explains what happened, and Daria states that he shouldn't've trusted them with such a power. Belly Bag says the only way to reverse the affects is through nerdy objects, but Uncle Grandpa says he's attracted to them already. The group gathers various nerdy objects and throws them on Beavis and Butthead, slowly reversing the affects of the Enchantment Enhancer. Finally, Daria throws her glasses on them (though reluctantly) and the affects are completely reversed. Beavis and Butthead are surprised that nobody wants to be around them, and Uncle Grandpa apologizes for not being able to help Beavis and Butthead score. The duo admit that they came closer to scoring than they ever have before. Uncle Grandpa bids them farewell as he goes through his checklist of kids to help (all of which are characters from different shows) as he makes his way to Gumball from The Amazing World Of Gumball to help.
