'Glee': 'Naked' Episode Features 'Men Of McKinley' Calendar (PHOTOS)

The "Glee" guys are getting naked!

In next week's episode of "Glee" -- appropriately titled "Naked" (Thurs., Jan. 31 at 9 p.m. EST on Fox) -- the New Directions need to raise money for Regionals, and Tina (Jenna Ushkowitz) comes up with the idea of selling a "Men of McKinley" calendar.

In a new video, the "Glee" cast gives a sneak peek of the calendar: Artie (Kevin McHale) is Mr. November in a pilgrim costume; Blaine (Darren Criss) celebrates the new year as Mr. January; Jake (Jacob Artist) is wearing nothing but a pumpkin as Mr. October; and Ryder (Blake Jenner) is dressed up as Uncle Sam for July.

"I can't really look at it," Criss says in the video on TVLine. "I think I look ridiculous ... Through the power of Photoshop, they can really kind of just draw some lines here ... maybe some pecs. [I] don't really have either of those."

Self-deprecating Jacob Artist looked at his October spread and said, "That's gotta be the ugliest looking pumpkin I've ever seen."
