Reminisce childhood/teenage memories and have a sweet and nostalgic cheap date!
Buy your favorite childhood cereals (you know, the ones your mom rarely let you get) and enjoy a marathon of your favorite old sitcoms together. I'm thinking Seinfeld, The Wonder Years, Saved by the Bell, Who's the Boss?, etc. To make this date cheaper, rent the tv sitcom dvds from the library.
Mmm, Berry Berry Kix and the first season of Friends...Now THAT would be a great date!
