On 'Mad Men,' Crista Flanagan plays an awkward and unlucky-in-love switchboard operator. In Playboy, the actress sheds that nerdy image -- plus, ya know, her clothes -- for a retro-inspired photo spread in the August issue. Random? Indeed. The 34-year-old Flanagan plays Lois Sadler on the hit AMC show, but only on the occasional episode. The role isn't even considered a supporting character on the show's Wikipedia page.

"Nobody's ever asked me to take off my clothes, or even kiss somebody" on the show, she told the lad mag. "I guess I haven't been seen as a sexy person, and sometimes not even as an attractive person."
