172: Catch Up! Listener Challenge, Puffy Snakes, Xenografts

It's our catch-up episode, and we got lots weird facts to share and special listeners to thank. Karen's back from her 5 million races over the fast few weeks and has so many stories to tell (involving dolphin poop and oddly-shaped cucumbers), and had so many real-life listener encounters! Colin's got some interesting news about scientists discovering the first and only (?) odorless vertebrate animal. A listener mailbag featuring a real xenograft encounter, and take our music quiz listener challenge! Email gjb.podcast@gmail.com with your answer! Learn more about your ad choices.
