The Ty-D-Bol Man. He was the guy who used to go boating in people's toilets. Just once it would've been so cool to see someone flush the toilet on him, but it never happened. The whole ad campaign seems so ridiculous in hindsight, but back then we didn't really think anything of it. I suppose I could've spent more time looking for decent pics, but really it's just a dude in a toilet..
On a side-note, it's amazing how much that guy looks like Mitt Romney..
