VIDEO: Charlie Day offers sneak peek of 'It's Always Sunny' Season 9 on 'Conan'

Charlie Day was on Conan on Monday to plug his genre blockbuster Pacific Rim. During his appearance, Day offered up a clip from the forthcoming ninth season (NINE?!) of It's Always Sunny in Philadelphia. The clip features Rowdy Roddy Piper as the gang tries to sell a bunch of folks on a pyramid scheme. Yes, Frank is shirtless and, of course, there's a llama involved.

The gang will be back in your living room every week starting in September.
