>>109841670I think the last time I laughed more at a show as when Chowder was still airing. It has a nice 2000's feel to it with the art style and jokes, especially since it uses more dark morbid humor akin to Billy and Mandy. That style of comedy as well as an emphasis on action gives the show a bite to it that most other shows this decade are lacking.
I'd recommend Not Impressed, Out Foxed, Bao Bao's Revenge, and Popularity Conquest as the top episodes of the show. A couple of them work better if you've gotten to know the characters more before hand, especially Not Impressed, but that's about an hours worth of content to give you a feel of the show. If you don't like after those ones, I wouldn't recommend the others.
