Ted Mosby:  Wha ... I do n't get it ! Why wo n't Robin tell me why she hates malls ?
Barney: Ted , you should be happy Robin has a secret . The more you learn about a person , the better chance you have of hitting the fatal " Ohhh ... " moment .
Marshall: The " Ohhh ... " moment ?
Barney: Yeah . That moment when you find out that one detail about a person that is going to be a deal - breaker .
Girl #1: It 's a promise ring . I made a pact with God to stay a virgin till I 'm married .
Barney: Ohhhh ...
Girl #2: I do n't have an eating disorder , it 's just when I put food in my mouth , I chew it and then I spit it out !
Barney: Ohhhh ...
Girl #3: I just turned _ 30 _ .
Barney: Ohhhhhh ...
Barney: So trust me , you want to postpone knowing anything about each other for as long as possible
Ted Mosby: Hmm ... I disagree . If there 's some potential " Ohhh ... " moment , I wanna know about it right away . I mean , what 's the alternative ?
Reverend Rob: I now pronounce you man and wife .
Ted Mosby: I love you .
Robin Scherbatsky: I used to be a dude .
Ted Mosby: Ohhhhhh ...
