Characters going clockwise: Edd, Tord, Matt, Tom
Eddsworld is an animated series on the internet that was created and formerly animated by Edd Gould. It features 3 characters:
Edd, who likes Coca-Cola and is usually the mastermind behind the plans,
Tom, who doesn't celebrate Christmas due to being a Jehovah's Witness and is also often drunk,
Matt, who's kinda stupid and very egotistical and vain,
and formerly Tord, who was Norwegian (I think) and generally the most violent of the four, often seen with guns and other various weapons. He left the show due to issues with the other cast members.
Sadly, Edd Gould died after a long battle with leukemia in March 2012, however Tom and Matt decided that the show must go on and have found a replacement animator and voice actor.Youtube channelNewgrounds channel
