Can you help me remember a game?

So, out of nowhere, I remembered playing a really funny RPG about 8 or 9 years ago (somewhere around the time Torchlight came out). I searched the internet with all possible keywords that came to mind and couldn't find anything. The style was cartoonish and the main character was a stocky knight who would say things like "These shiny metal plates are made of metal!". He had a really deep masculine voice, but was goofy overall. I remember there were many different settings, including a graveyard with zombies and a forest with unicorns. I'm not sure, but I think in one quest he had to collect unicorn poop for something.

I can't believe that this game could be so easily forgotten. I really wish to find it again, maybe make some giveaways on SG. Halp?
