IASIP (Charlie Day is my fave)

For those who are not aware of that acronym, It's Always Sunny in Philadelphia. If you haven't watched it, you should. Right now it's in reruns every Monday night for two hours (9 to 11 EDT, or 8 to 10 CDT) on Comedy Central. It's an FX original and it's funny as shit.

It's as wrong as wrong can be for a basic cable show. The word shit is used often, as is asshole and goddammit. Oh yeah, son of a bitch and dick are also tossed about, along with various tenses of the verb bang, so it's not for prudes. If you have a good, sick sense of humor and you have not seen it, please do yourself a favor and watch it.

It's about two siblings--twins actually--Dennis and Dee and their "dad" Frank, along with Charlie and Mac. Together they own Paddy's Pub. They are shallow, manipulative, narcissistic, and drunk. Tune in if you know what's good for you. Season 7 starts filming in about a month, so come September you will find brand new episodes. Until then, watch Monday nights or buy the DVDs.
