The genius of Seanbaby is that he takes ridiculous things and tries to make them even more ridiculous. And he always succeeds.
While The Onion's success has always been in taking serious news and parodying it by writing about it in a straight manner, Seanbaby takes things that people know are silly, such as Nintendo and Hostess Fruit Pie Ads and making them even sillier and sillier, until he reaches heights of comedic contortion that have to be read to be understood.
The description hardly does Seanbaby justice however, he has to be read to be understood. So go on to seanbaby.com and get your read on.
