'It's Always Sunny' actor Charlie Day talks 'Horrible Bosses,' talking dirty with Jennifer Aniston

"Here's good thing about being naked with Jennifer Aniston: Nobody will ever look at you. I'm as good as invisible," says a relieved Charlie Day, about a scene in "Horrible Bosses," out July 8.

We caught up with the "It's Always Sunny in Philadelphia" actor yesterday at the Sofitel about the film, in which he co-stars with Jason Bateman and "SNL" actor Jason Sudeikis.

Day, who will be shooting "Sunny" in the area for the next few weeks along with its South Philly-native creator Rob McElhenney and the rest of the cast, says that "Anytime I go anywhere people come up to me and say, 'Hey, Dude, I'm from Philly too,' so I think that's a pretty good sign of being an honorary Philadelphian."

Day's "Horrible Bosses" character, Dale, is constantly sexually harassed by Aniston, who demands sex from him, with extremely descriptive language.

"Those words sound weird coming out of her mouth. She says a lot of dirty things," Day says of Aniston.

The actor, whose wife, actress Mary Elizabeth Ellis, is in town with him visiting friends, said he, Bateman and Sudeikis had a great time making each other laugh during the shoot.

As for the "Sunny" shooting, Day is excited for the FX show's seventh season and promises that the gang is "up to our usual tricks."

When we wrapped up our video interview, which you can watch today at PhillyGossip.com, talk turned to the car-crash death early yesterday of "Jackass" star Ryan Dunn.

Day said that he had met Dunn a few times and that the "Sunny" gang had been hoping to get him to appear on an episode next season.
