1x15 - Everybody Loves Raymond

Debra, already annoyed at getting stuck driving the old car Ray bought from his parents, really gets upset when she discovers that it was his old "make-out-mobile." Debra had been unable to understand why Ray wanted so desperately to buy his parents' old car, until Robert mistakenly blurts out that it's the car in which Ray first "got lucky" as a teenager with his girlfriend. Imagining what might have happened in the car during its earlier life, Debra decides not to drive it again.
