Angel season 5 is now rerunning on TNT, I think they are up to the episode where Spike is sent to a hell dimension.

Smallville Season 4,of course.(thats basically all the WB is good for,nowadays)

My CN fav's : Teen Titans/Justice League Unlimited/adult Swim (Although I havent been keeping up with it)

Real World Season 15: Philedelphia (hooked on this show,and the reruns)

ohh,and how could I forget the occasional reruns of jackass,and boiling points?yeah,those rock.
