Expectant mothers have a lot to do before the baby arrives: baby-proof the house, assemble the crib, install the car seat. But when there's someone as charming as Chuck alum Ryan McPartlin around, thosee tasks suddenly become a lot less mundane.

In this exclusive clip from USA's new comedy Playing House (April 29, 10/9c), mom-to-be Maggie (Lennon Parham) and her best friend Emma (Jessica St. Clair) enlist the help of a handsome police officer named Steve (McPartlin) to "get up in there" and show them how to strap in the car seat nice and tight.

"I would love to feel the tightness that you're talking about," Emma says she and Maggie lean in real-close to get a good view.

However, the ladies' friend and fellow police officer Mark (Keegan Michael Key) rudely interrupts Steve to do it himself. But the sexual innuendos don't stop there.
