Quote from Barney in The Drunk Train
Future Ted: [v.o.] That night, Barney and I found ourselves in a strange, new universe called... The Drunk Train.
Barney: Where has this heavenly vehicle been all my life? Can you hear its inspiring chant, Ted? I think I can get laid, I think I can get laid. It's-it's The Little Engine with Wood, The Whore-ient Express. The Long Island Tail Road!
Ted: Oh, I got one. Thomas the Spank Engine!
Barney: Ted, that is a children's book.
