Good mention, I don’t remember if anyone noted the second series before. It’s easily as funny if not funnier than the first, and like the first is a good intro to how a D&D session typically goes.
Brilliant Gameologists is also worth checking out if you’re really into RPGs. They take an incredibly detailed approach to issues that tend to come up in gaming (different playing styles, etc. ), and stir in an amazingly foul-mouthed reparteé. Good times.
