Quote from Barney in The Fortress
Barney: I've been thinking and I realized something. The Fortress of Solitude is where Superman went to be alone. And I never want to be alone again. Robin: Thank you, Barney, that really... Barney: But then I remembered in Superman II, Superman gave up all his powers to be with Lois Lane, and he was honestly kind of a vag after that. Robin: Oh, buddy, just quit while... Barney: Now, Superman III was a complete train wreck totally. Robin: What's your point? Barney: That... that I love you. And I'm giving up my apartment for you. And that the Superman films are uneven.
