Glee is fun, I've seen a couple episodes, although I'm not sure they can keep it up …
Three awesome, yet relatively short-lived shows: Dead Like Me, Wonderfalls and Pushing Daisies. The latter is still ongoing from what I've read.
If you know one, the others are kinda like that. Dead Like Me is about an eighteen year old girl named "George" and her "life" as a Grim Reaper after having died from being hit by a toilet seat from space. The humor reminded me of Office Space (the movie, I don't know the series). Wonderfalls is an inspirational series about a young, laid-back woman called Jaye who for no apparent reason finds herself hearing inanimate animal objects tell her to do things. And Pushing Daisies is a colorful, fairytale-like story about a pie-maker called Ned who can bring dead people back to life by touch, but only for a minute lest somebody else die.
Lots of good-natured fun, a little morbid at times (obviously.)
