Unca Rish here. I was really pleased to be given the chance to read a holiday story on Podcastle (and vexed when they said they'd already asked once and I hadn't responded), and it turned out to be "The Christmas Mummy," by the lovely Heather Shaw and the almost-as-lovely Tim Pratt. And hey, they rated it G.
Go over and give it a listen. If you've ever wondered how horrible the show would be if it was all-Rish-Outfield-all-the-time, this is your chance to find out.
