Context: Especially since the majority of our conversations quote either Pretty Woman , Steel Magnolias or Shag . However , once in a while we will each reference a movie and look over to see that the reference has been completely lost on the other . This is disastrous , especially when it 's as good of a reference as the other day when we were watching a re - run of Friends and Tate Donovan was making a guest appearance and I referenced Space Camp . And Evan did n't know Space Camp !

Options:
0. Because it was disastrous .
1. They did n't understand it .
2. Tate Donovan may not have made a guest appearance .
3. None of the above choices .
