It has been awhile since we've seen Mr. Gravesite (did not know his name was Wastrel). I thought this was going to be a legitimate riddle with a bad pun at the end but no, it's just a lesson to not trust homeless vagrants.
I am highly disappointed in today's strip but I'm highly disappointed by all the strips so what else is new. I guess I'm all for actually learning Gravesite's full name so I guess the strip isn't a total loss.
