Uncle_Dolan
Dolan is an MS Paint web comic series featuring a variety of poorly drawn Disney cartoon characters. The main character Dolan, based on Donald Duck, is often portrayed as a psychotic killer and sex addict.

Dolan began on a Finnish message board with a comic of Donald Duck that was done in MS paint. Many people stated that the comic was poorly drawn, and it was accompanied by a bad English translation. Then it showed up on a 4chan "you laugh you lose" thread. Then it has gone all around 4chan, Reddit, Tumblr, and The Memebase.
