I am trying to think if I ever wore purple underwear before. Probably yes, but I am 100% positive I've never worn Calvin Klein ANYTHING before. If I went back in time and my hot-to-trot young mother started calling me by the name on my tighty-whities, she'd be very confused as to why my name was "Caldor."Luckily that has yet to happen. But today, it happened for Marty in another classic scene.
