On 'Lie to Me' (Mon., 9PM ET on FOX), Dr. Cal Lightman is paying Detective Wallowski a visit when some gang members break into her house. Lightman and Wallowski have just enough time to set a fake romantic scene -- low lighting, "sexy music," candles and strewn clothing -- that will lead the intruders into her bedroom.

Sure enough, the gang leader charges in and sprays the room (the bed, in particular) with bullets. But Lightman and Wallowski are hiding in closets and armed with guns from a hidden rack ("My dad said always have options"). They work together to bring him down and scare off his accomplices.
