Looney Tunes, an animated comedy short film series, marked the Golden Age of American animation. Looney Tunes, together with its accompanying series Merrie Melodies, introduced to us such iconic characters as Bugs Bunny, Daffy Duck, Porky Pig, Wile E. Coyote, Marvin The Martian, and plenty, plenty more! Each of these characters had their own skits assigned to them, but it was Bugs Bunny that eventually stole the show, becoming the leading rabbit of the universe. And, if you're into classic animation, Looney Tunes is basically a manual to the genre!

Tom & Jerry is by far the most well-known animated series franchise consisting of 114 short films in its original run. Of course, you are right, there are plenty more of these comedic skits, but we're only talking about the episodes created by William Hanna and Joseph Barbera since the duo was the first to bring Tom and Jerry to life. It's the story as old as the Earth itself depicted here - the constant chase between a cat and a mouse. However, in this series, the cat never wins, and the teeny tiny mouse proves to be way smarter than the predator! The fun here never ends, and their adventures get more and more elaborate with each skit. A true classic in the world of animation!

If Futurama has always seemed oddly familiar to you, then you're right, as you definitely have seen the other famous creation by the same writer Matt Groening, and, yes, it's The Simpsons. But, though such a prehistory of Futurama might lead you to imagine the same Simpsons just in space, boy, are you wrong. From gut-wrenching events (don't tell me I didn't warn you about The Dog) to subtle and not-so-subtle adult humor, this show is not just another animated series but an excellent sitcom undoubtedly worthy of being on this list. And if seven seasons of Futurama aren't enough to quench your thirst, you can always watch one of the series-based movies, play a video game, or collect the official merchandise.

An animated series that's old enough to gamble, buy beer, and smoke cigarettes, South Park has been running since 1997, gracing our screens with its dark and surreal humor, satire, and loads of profanity for 24 years.

Many famous people and popular stars have agreed to appear on this offbeat show - starting with Elton John, Jennifer Aniston and ending with Ozzy Osborne; the series had loads of well-known guests. However, some of them appeared very much incognito, for instance, George Clooney, who provided the barks of Stan's dog. Stars or no stars, though, the animated series is truly iconic and impactful, an inseparable part of popular culture.
