All of them. I nearly always get into shows late. I'm not a big fan the "WATCH EPISODE, WAIT A WEEK, WATCH ANOTHER" method of episode distribution that is all too common. I don't like being fed in increments like a child, like a mangy mutt, like a worthless bitch, like a ravenous whore, like a filthy fucking tandiberry, no sir! In stead of the traditional viewing method which many go along with, I prefer to wait until a show has finished at least most of its first season, if not more. This is good because there's always new shows coming on, so I can just watch older ones (such as Seinfeld, for example - though I'm sure you didn't need one, you sly devil, you) while I wait for the newer shows to finish up a bit. Often times I will download an entire season, or series, and burn through it all in a short period of time. Nevertheless, I prefer to watch television at my leisure, and not whenever it is served to me! Anyhow, here is a (partial, perhaps) list:

Lost
Frasier
House
The Office
Scrubs
Frasier
Curb Your Enthusiasm
Oz
That 70s Show
Nip/Tuck
Frasier
The Sopranos
Breaking Bad
Monk

and hopefully several more to come, pending that I deem future television shows worthy of my viewing time, of course.
