Thank you, devoted listeners, and welcome to our informal fifth anniversary. On today's show, we're delving into the mailbag to help out some of you with your (mostly bodily function-related) issues, but we've also got some good good space bants in there too for you highbrow types. This episode's mistakes include:

• Not enough poop talk.

Stare into the cavernous void of space, then like us on Facebook, follow us on Twitter, rate us on iTunes, and send your questions to [email protected].
