Really good show. It's TV-14 most of the time, but towards the end of the first season (the show only has 1 season so far) it transitioned to TV-MA. The season finale, "The Manbirds" had a lot of sex/language/violence. Lots of swearing like "g*ddamnit" "J*sus Chr*st" "suck my b*lls" and "t*ts" and sex references like "Gimme a squirt!" Also lots of references to p*nises in this episode. The Manbirds participate in "c*ck fights" (uncensored because it's a double entendre) in which they wear boxing gloves over their genitals and fight. It's pretty hilarious, but onviously adult-oriented. And Doug the Koala is adorable.
