The Amazing World of Gumball is a massively underrated show. Personally, I find it to be totally on par with Adventure Time -- sometimes even better -- but I don't think it's as out there as it should be with regards to viewers over the age of say, 9? It's definitely not a show just for kids, alot of secret innuendos that children wont get, with the type of random humour you'd find in a Family Guy episode. 

Anyway, I love it, and here's a little piece I had a lot of fun (and frustration) doing, but pretty pleased with the results.
