I happen to be a big fan of animation series, ever since cartoon Network has turned into pretty much of a joke, I gave up on cartoon.. I mean they were days when shows like Johnny bravo, Powerpuff girls, Dexter laboratory, kids next door, Megax XLR had something for everyone including adults( not forgetting Tom and Jerry, that one seems to be a big hit with the adults)
to cut long story short Sha, I stumbled upon the Boondocks and I swore it was the funniest "adults" animation series ever, the humor, storyline, pop culture references were quite hilarious and it seemed to me like no other show for me could beat it..
And then I devoted my time to Family guy and was proven wrong and later SOUTHPARK proved to be equally as good as the others.. so I'm asking which is really the best adult animated series of all time

THE BOONDOCKS:The Boondocks is an American adult animated sitcom on Adult Swim . Created by Aaron McGruder,based upon his comic strip of the same name.the series premiered on November 6, 2005. The show begins with a
black family, the Freemans, settling into the fictional, peaceful, and mostly white suburb of Woodcrest.The perspective offered by this mixture of cultures, lifestyles, social classes, stereotypes, viewpoints and racial(ized) identities provides for much of the series' satire, comedy, and conflict.

FAMILY GUY:Family Guy is an American adult animated sitcom created by Seth MacFarlane for the Fox Broadcasting Company . The series centers on the Griffins, a family consisting of parents Peter and Lois ; their children Meg , Chris, and Stewie; and their anthropomorphic pet dog Brian. The show is set in the fictional city of Quahog,
Rhode Island , and exhibits much of its humor in the form of cutaway gags that often lampoon
American culture .

SOUTHPARK:South Park is an American adult animated sitcom created by Trey Parker and Matt Stone and developed by Brian Graden for the
television network , Comedy Central . The show revolves around four boys—Stan Marsh, Kyle Broflovski, Eric Cartman, and Kenny McCormick
—and their bizarre adventures in and around the titular Colorado town.
