To catch Alex using a condescending tone, 'Whitney' (Thu., 9:30PM ET on NBC) set up a hidden camera in the apartment. Only, after taking his brother to an after-party, Alex stopped by Mark's apartment, where he saw the camera feed on the TV.
Rather than have Mark shut it off, Alex decided to put Whitney on the spot. So when he knew everyone was downstairs watching, he decided to redeem that birthday coupon she'd given him for a free lap dance any time.
What followed was one of the most awkward sexy lap dances you have ever seen. We were actually disappointed that he stopped her by telling her he knew about the camera. He could have milked that one all evening by having her embarrass herself in front of the camera.
