When you think of Playboy, you probably think of wanking, not planking. But Hugh Hefner, sweetie that he is, tried out planking evidently to amuse his new number-one girl, Anna Sophia Burgland.

“I got Hef to plank!” the Daily Mail relates Anna as having posted on Twitter, with a picture of one of the great men of American letters (and figures) laying face down on his dining room table in black silk pajamas with post-party-type cups and glasses near his head, looking like he passed out there after an especially awesome debauch.

A subsequent picture shows Hef getting his investment back seven times over: seven bunnies all planked on the table with Hef at the head: “Included are Anna, Hef's "second" girlfriend Shera Bechard, Miss January 2010 Jaime Edmondson, Miss March 2009 Jenn Pershing, Miss October 2010 Claire Sinclair, and Playboy models Trisha Frick and Cristal Camden, who was one of Hef's seven girlfriends in 2003.”

Planking, by the way, is a fad in which the person lays face down, hands at their sides, in an unusual place and gets a picture of their bizarre pose posted on a social networking site. In case you didn’t work this much out for yourself, it’s so-called because you look like a plank of wood. Here’s a Funny or Die video in which young celebs come out against planking.

So it’s not a tinny pursuit—it’s good and woody. Especially at the Playboy Mansion.
