Knights of the Arcade is a Pittsburgh PA based comedy show that performs a very rules light sketch comedy adventure set to Dungeons and Dragons. They perform monthly in front of a live audience but they also record all of their shows and have a podcast.
I have had the pleasure of being to their shows and literally thought I was dying from laughing so much (like the weasels in Roger Rabbit, yes I went there).
Here is their promotional video and I will provide links to the page and where else to connect with them. These folks are truly amazing.
If you want a good laugh every month definitely check them out. And if you are a Pittsburgh resident, I HIGHLY recommend going to see their show.
