Just looked them up. Hilarious!
I hope "Surly" talks.......
The Duffs' names are Tipsy, Queasy, Surly, Sleazy, Edgy, Dizzy and Remorseful. The only Duff that speaks is Surly. True to his name, he has a surly and cynical demeanor. He says things like "Hey, Surly only looks out for one guy ... Surly!", "Shut up" and "Take a picture, it'll last longer. Get outta here!" [1] Also, while waving to people at the Duff Dayz Beer Festival, Surly says in a loud voice, "Drink Duff!", then covers his mouth with his hand and adds, "Responsibly," in a much quieter voice.

I love it.
