I highly recommend watching or listening to the glass cannon network play through of this (unless you don't want to spoil the plot for yourself). It's across roughly 50 episodes and it's one of the best things they've ever done. All the characters are interesting and their descent into madness is performed exceptionally well.

It's referred to as Get In The Trunk seasons 4-6 but you don't really need to have heard the first 3 (although they are good).
