Has anyone explained to him the idea of a punchline? That whole "Hulk" thing went nowhere, and the "when you're dating online you meet men pretending to be ladies" set up led to a punchline of "when you're dating online you meet men pretending to be ladies". I know I shouldn't expect his "jokes" to be any good, but... this is horrible even for him.

This is a guy who has taken the encouragement of his nephews' laughing far too seriously. He really just has "uncle" written all over him, with slight hints of "closet pedophile."
Also, how can he have a huge belly but more-or-less muscular and lean thighs? Fat doesn't work like that. You're a mystery and an enigma, DS.
