Meet Tina Marie Arie and Howard Windham.

The Texas duo was arrested on drug charges last Monday after a cop was summoned to a Whataburger, where a male acquaintance of Arie and Windham was passed out.

Arie, 44, who admitted providing the unconscious man with Hydrocodone, was arrested for delivery of a controlled substance. Windham, 30, was collared on a possession rap after he was found with the painkiller Soma. The pair was cuffed and stuffed into a police cruiser for the trip to get booked.

That’s when things got interesting, according to a spokesperson for Montgomery County Constable Precinct 4. When the officer looked in his rear view mirror, he “could no longer see Tina Arie,” who subsequently explained that she was resting her head in Windham’s lap because she was “tired.”

Suspicious, the officer pulled over to the side of the road to further investigate, according to a press statement. He discovered that, “despite being handcuffed behind their backs,” the pair were engaged in a sexual act. Windham’s jeans were undone “and Arie was servicing his exposed genitalia.”

It is unclear how Windham’s jeans were unfastened--or whether teeth were somehow involved in the undoing of said britches. A spokesperson said she was unaware whether the jeans were of the zipper or button-fly variety.

The lewd Houdini act (Lewdini?) abrupty ended when the cop “ordered them to cease sexual contact.” Though Arie and Windham could have faced an additional public indecency charge, they apparently caught a break when investigators opted not to tack on a misdemeanor count to the more serious felony narcotics charges.
