The good people of Epic Meal Time, who previously brought us the greasiest sandwich in the world, recently created either the best or the worst corndog ever made (depending on your point of view). It's made of 18 slices of bacon with the bacon grease turned into a sauce, a pound of ground beef, and 3 hot dogs wrapped in cheese. The chefs drenched this concoction in corn meal and deep fried it. At the link, you can watch a video of its creation and consumption.

Agreed, although I think it would be ok if it was just a giant hot dog (or multiple hot dogs) and bacon. The ground beef is what breaks the deal for me (although, really, what is a (kosher) hotdog but ground beef?)
A corn dog is a hot dog dipped in a corn meal batter and deep fried. The only exception would be the use of those hot dogs with the cheese inside them.
