Friend of my wife's was getting married. I have no idea why, because every time I met her (the friend) all she did was bitch about her fiance.
Well one day she's complaining that her fiance went out and bought a new car without consulting her and the monthly payment was too much for them to afford. So, to get back at him she bought her own new car.
(the marriage lasted < 2years and both cars got repo'd)
