Quinn here.
On the 1/13/12 show Walt makes a request for a listener to make him a paper mache Day Of The Dead skull. He is willing to trade a page of original artwork from War Of The Undead or Batman to whoever can make him a skull that looks like this –
Day Of The Dead Skull
I know he needs it to look pretty good, so please only contact Walt about it if you know you can make it top notch.
I know it’s for a pretty exciting project, so you’ll be happy to have been a part of it.
Good luck!

Tell 'Em Steve Dave! 
I would love the chance to be able to do something for you guys! Im confident I can meet or excede your paper mache expectations!
Does it have to be paper maché or would clay work? What scale does he want?
