Tuesday marks the DVD release of ‘A Very Sunny Christmas,’ the ‘Always Sunny in Philadelphia‘ holiday special, and according to the cast we have a naked Danny DeVito to look forward to.

“Danny’s getting naked,” Kaitlin Olson – who plays Sweet Dee – told us at the DVD release party last week. “It really threw me for a loop. I knew it was going to happen but once it did I was – it’s a lot to handle…Get your pause button ready because — my God!” She warned.

What else is in store for us in this very naked episode? “Dennis and Dee hate Christmas because Frank was always terrible. He always gives them gifts and then takes them away.”

“They try to show him his past, present, and future to try to change him and make him a better person,” she added. “It ends up not going well.”

Rob McElhenney (Mac) also gave us the scoop about what kind of trouble the gang will get into the rest of the season. “I know we go back to college. We go back and try to punk out some frat guys,” he said, adding that we’ll also learn more about one guy’s art of seduction. “Dennis walks us through his system of seduction, which is how he winds up getting so many women.”

Is there any chance we’ll see a follow-up to Charlie’s epic rock opera “The Nightman Cometh”? Day says, “At some point in time we’re going to have to get the music going again. It’s not going to happen in the fifth season but maybe in the sixth season.”

‘It’s Always Sunny in Philadelphia: A Very Sunny Christmas’ debuts exclusively on Blu-ray and DVD November 17.
