I like me some Christmas and I really need it this year but I would never think to listen to a Christmas based podcast. But, if you want to get really meta and listen to a podcast about other podcasts and those podcasts are Christmas themed then the aptly named Christmas Podcasts Podcast will give you your fill of Santa.
Obviously two California Ur Holiday seasonals should be the choice here. Get an Anchor and a Sierra Nevada Christmas beer and find some cheer in a very bad year.
