As an amateur podcast guest, please hold your applause until the end of the blog post, I'm also mildly addicted to podcasts. If I'm driving, I'm listening to podcasts and at about 4 hours of driving time a week I've got time to kill. Since the death of my beloved Superego, Paul F. Tompkins has made his own improvised sketch radio show to ease the pain. It's much more informal and under produced which isn't necessarily worse... just different.
It's still funny as hell and I dare you to find a comedian that's this funny just talking to himself. As improv comedy goes you're gonna like some more than others but I'd say the hits outweigh the misses for the most part. Though I'd keep an eye out for any episode with Brandon Johnson or anyone from the Superego crew.
Do have a listen.
