I bet this guy's tobacco was too dry so it burned too fast and got too hot

ok ok ok, ribbing aside I do prefer moist tobacco and I've been doing it long enough to know what I like. Different strokes for different folks.

anyways I'm off to go lick a wet dog and eat some damp cardboard for dinner.

You are correct, different strokes. Enjoy dinner, you made me laugh.
