Used Karma - S5.E7

When Greg starts to dress and act strangely after driving the used car Dharma recently bought, she worries he's been possessed by the spirit of the car's previous owner, a petty criminal and gambler who met an untimely death. Meanwhile, Edward has Larry set up a security camera at his house to help catch the kid who eggs his house every Halloween, but the ""trick"" is still on him.
