Duff

Duff is a quiet man when you first meet him yet is incredibly observant and always listening. He takes his time in both thoughts and actions, but in the end is always ready to share the very best of himself. Duff is strong yet gentle, firm yet kind and mushy. If you are lucky enough to have a Duff in your life, then you are guaranteed a funny and generous confidante who will be by your side forever.

You know it's going to be a great night, Duff is coming!
