The "Original" prank call podcast, as far as I'm concerned. I've been listening to Brad as long as I can remember, and he's got an archive of calls that goes back decades.
He's a prank caller with heart, which happens to be a common thread among prank callers I really enjoy. He has mastered the art of prodding at people who he knows will get angry with him, being kind to people who he can tell are in obvious distress, and above all, he's got a knack for the absurd. Some of the pranks that he manages to get people to fall for blow my freaking mind.
Great podcast. Worth checking out if you're into prank calls and haven't heard it, although I honestly am skeptical anyone into pranks wouldn't have stumbled upon TSPS at some point.
