I have to be honest with you; you will never be as cool as Duffman.  It's simply impossible.  However, there's no harm in trying.  Being just a little more like Duffman will get you a lot more action, oooooh yeah!

The first step in becoming more like Duffman is dressing like Duffman.  This means wearing a standard super hero suit, complete with male-support strap and the Duff logo across the chest.  A red cape is the perfect accessory to this suit, since it creates the illusion that you can fly.  The most important part of Duffman's attire is the belt complete with beer cans.  This enabales to party anywhere, any location.  To be cool like Duffman, you must always wear sunglasses, even at night time or when you're inside.  Sunglasses increase your coolness level by at least 10 points.  The perfect complement to the sunglasses is a Duff logo hat, which you can buy at the Duff Brewery or any Kwik-e-Mart location.  Lastly, to look as cool as Duffman, you need a pair of white gloves and a wig on your chest.  Remember this:  Duffman would never wear a plastic smock with a picture of his face on it, not even on Haloween.

The last step in obtaining the coolness of Duffman is learning how to dance like Duffman.  I can't explain how to do this.  Just watch Duffman and eventually you will learn.
