Having started in the early 2000s as an internet flash-animated short series as one of its author's hobbies, Alejo y Valentina not only became a huge influence in Latin American internet youth culture. Some of its absurd random humor is still in the collective unconscious generation's mind. When MTV and the show's creator, Alejandro Szykula signed for seasons of exclusive all new episodes, Alejo y Valentina was not so less popular than it later became. Spanish is a must since it hasn't been translated to other languages, and it has lots of Argentinian culture related puns and jokes too. It is some sort of Happy Tree Friends meets Don Hertzfeld's "Rejected" with some sort of early South Parkish aesthetics. Totally worth watching.
