Panel 3 bugs me the most here. It feels like Brent and Francis have become finger puppets for Kurtz's views on the matter. Francis looking at the camera in the last panel doesn't help either. The whole thing just feels forced.
The Canterbury Tales was a bunch of people sitting around telling dirty stories, not sitting around having a fart contest. There's a distinct difference.
Art nitpick: Panel 2, what's up with Cole's shirt collar?
