This week on 'It's Always Sunny in Philadelphia' (Thu., 10PM ET on FX) the gang went to the Jersey Shore so that Dennis and Dee could try re-living their magical childhood.

However, it seems that things on the boardwalk have taken a turn for the worse since then, and not even some Bo Derek cornrows or a sunscreen bottle full of tequila could make it better for the gang.

Somehow, the hapless Dee and Dennis end up getting high on PCP and then are accomplices in an armed robbery that goes tragically wrong.

It's like '10' meets 'Casino' as the pair are told to "DIG!" a grave in the sand.

The cast of the FX sitcom It's Always Sunny in Philadelphia gathered a stone's throw from Beverly Hills this week to celebrate the release of the show's new Christmas special.

A Very Sunny Christmas arrives on Blu-ray and DVD November 17 from Twentieth Century Fox Home Entertainment. Fox teamed with Maxim Magazine to hold a festive bash last Thursday night at Guys and Dolls Lounge in the shadow of Cedar Sinai Hospital on Beverly Blvd. (Event gallery below.)

A modest red carpet set-up gathered a cramped collection of reporters and photographers together to greet the arrivals of show stars Danny DeVito, Kaitlin Olson, Rob McElhenney, Glenn Howerton and Charlie Day.

As if looking to mimic the bleak Philadelphia winter, rain sprinkled the LA streets in the hours leading up to the event -- and temperatures hovering in the low 50s made it a goose bumpy night for the several cocktail dress-clad ladies mingling in the crowd.

One of the most terribly underrated comedy shows on television today is FX's It's Always Sunny in Philadelphia. Here's a hot tip for any Americans that have yet to experience the delightfully atrocious characters from the show: Get on it. Hulu is rolling through all of the episodes and they've just started at the beginning (first five episodes are now available). Perfect time to start, kids.

For those that are already a little more well-versed in the Always Sunny universe, there's fun stuff for you, too. The gang is taking an It's Always Sunny in Philadelphia tour to perform a live stage version of one of their most popular episodes, "The Nightman Cometh."
