September will be a big month for Glenn Howerton It's Always Sunny in Philadelphia , where he serves as a writer, executive producer and of course an actor -- playing the ever narcissistic Dennis -- is back for Season 5 , and Howerton will also soon be frequently heard on FOX's new animated series, the Family Guy spinoff The Cleveland Show

I recently spoke to Howerton about It's Always Sunny and what's to come, along with what it's like to enter the world of animation with Cleveland

We're doing a good mix this year of some good topical stuff and newsworthy kind of stuff and then also doing smaller episodes that are more relationship based. Kind of like last season, we had " Mac's Banging the Waitress ", which was really just a small, very contained episode with just me and Mac and Charlie and The Waitress . So yeah, this year we're tackling some of the things that are happening in the news, like the mortgage crisis and the economy. We're also doing an episode where we put on a big wrestling match for the troops coming back from overseas - that's a really good one. But then we're doing some smaller stuff, like Mac and I decide not to be roommates anymore. We decide to take a break – it parallels a divorce scenario. And all of our relationships of course get pulled into that awful world of having to deal with our divorce.The Waitress is getting married. We throw an intervention on Frank , because he's pretty much getting out of control. He's just getting wasted all the time and he wants to bang our dead mom's sister. All kinds of crazy s**t, man. It's gonna be great!I honestly have to say, this season is going to be really good. Rob [McElhenney ] and I have been sitting in the editing room every day. We haven't had Charlie [Day ], because Charlie's shooting a movie in New York. So we've been without Charlie this year, which is weird. But I've got to say, these cuts that we're working on… By this point, we're usually just sick of these episodes, but they're still making me laugh, so that's a good sign.I don't want to give away too much. I will say this – Mac and I and Charlie have created a triumvirate tag team called the Birds of War. And there is a Birds of War theme song that we come out to. There's great Birds of War costumes. And most exciting of all is that Rowdy Roddy Piper is going to be in that episode. I grew up watching that guy wrestle. I'm actually reading his autobiography right now, which is just extraordinary. He's a great guy. He's an interesting cat.Yeah, they want us to do that, actually. There's a very good chance, if the dates work out, that we may be doing that sometime in September. We'll see. It's not definite. If we do [go on RAW], our plan is to come on as the Birds of War. We may have a little bit of beef with somebody. We'll see.
