For those of you interested, Keaton is on the WTF Podcast today. I haven't listened to the whole thing myself yet, but since it's primarily a comedy podcast they discuss Keaton's stand up past first before moving into Hollywood and Batman. I love Maron's podcast and standup, so maybe this will also bring some of you guys in. Enjoy!
