Showtime's 'Homeland' bringing lie-detector to Philly

Could you beat a polygraph?

Most of us, if we're lucky, will never be forced to find out under conditions in which the results actually matter, but Showtime, looking for a way to promote its insanely addictive CIA series, "Homeland," is bringing the lie-detector to the masses this week, with a stop in Philly on Thursday.

Why? Because at least one character on the show, which stars Damian Lewis as a former al Qaeda prisoner and Claire Danes as the CIA analyst who's convinced he's a terrorist, appeared to have beaten the test in Sunday's episode.

But then, I'm not always sure that what I see on "Homeland" is what I'm meant to believe.

Anyway, if you think you have the chops to lie under pressure and get away with it -- not exactly a skill you'd want to brag about to a spouse or a boss, perhaps -- here's where you can go to prove it:

    Reading Terminal SE Corner of N. 12th St. and Arch St. (11 a.m.- 4 p.m. Thursday, Nov. 10).

 Can't make it in person? There's an app for that. (Naturally.)

Visit http://www.sho.com/site/homeland/polygraph.sho to take a virtual lie-detector test, using a webcam and microphone. Unfortunately, it also requires logging in to your Facebook account. And is your ability (or inability) to lie without flinching really something you want to share with your so-called friends?
