Louis C.K. is currently one of my favorite comedians. His show on FX called "Louie" (the phonetic spelling of his first name) has been on for going on three seasons now and it's really a good, interesting, show.
I've got Seasons 1 and 2 on DVD (Season 3 is currently running, presently on a mild break mid-arc centering around Louis taking on the Late Show mantle pending the departure of Letterman) and just watched the episode "Duckling." A double-length episode featuring the Louis C.K. going on a USO tour in a Afghanistan and it's just a good, charming, episode that's not quite in tone with the rest of the series (usually featuring Louie truing to lead a regular, miserable, life as a divorced father of two making a living as a stand-up comedian in New York.)
If you've not seen the series I recommend it. It's not quite a "sit-com" but no a "Drama" either. It's a show that's hard to describe and it really only has Louis as a regular character (his daughters, friends and some family members are on-and-off parts.)
But I certainly
recommend seeing the episode "Duckling" which I assume is available either through Netflix, Blip or some other online viewing method.
