Burger World's new soda turns Beavis back into Cornholio, and Immigration believes he's an undocumented immigrant.
- Artistic License – Geography: No, Beavis, Lake Titicaca is not in Nicaragua, it's on the border of Peru and Bolivia. The Border Patrol seems just as confused, hence why they just send him to Mexico alongside the other immigrants in the hopes that their authorities could sort out the rest.
- Gratuitous Spanish: Cornholio speaks a mix of legitimate Spanish and gibberish. In one scene, he refers to sugar by the Spanish word "azúcar."
- On the bus, several immigrants speak this.
- Karma Houdini: The Immigration agent and his superior never suffer any consequences for deporting Beavis, let alone being fooled to begin with.
- The Illegal: The Border Control thinks Cornholio is an undocumented immigrant, and return him to Mexico at the end.
- Must Have Caffeine: Beavis turns into Cornholio as a result of Burger World's new soda, Volt Cola. Later, he stays as Cornholio by pouring sugar into the coffee pot he finds at the Border Patrol's office.
- National Stereotypes: The Immigration officer arrests Cornholio because he exhibits Mexican stereotypes, the cinch being that Cornholio ate his burrito and taco combo during the car ride over.
- No Ending: Beavis - still Cornholio - gets stranded in Mexico, thinking it's Nicaragua - and the episode ends there.
- Politically Incorrect Villain: The main antagonist, in this case, is the Border Patrol, who falsely assumes Beavis as a foreigner for speaking in an incoherent language and his strange actions, implying they are very bigoted.
- Take That!: To Border Patrol, who are shown to be highly racist and arrest Beavis on Mexican stereotypes.
