Why does Jenkins look like a hobo?

It been an on-going trend for him to dress (get dressed) in basically clothes you'd wear at home and maybe go to the store next door. I like him as a caster and an analyst but wearing a a home-made sleeveless shirt and some shaggy looking pants is just making him look very unprofessional. Also in most cases I can't find a spoof or a funny bit which would make it necessary or add any comedic value (Slacks being dressed as CM had a purpose). Also all the other people on the panel wear nice clothes.

I'm all for dressing down b c'mon give the guy a fking T-shirt at least.
