Quote from Ted in Spoiler Alert
Ted: Well, thank you, pal. You and your little friends, you just had to tell me. You just had to give in to my incessant begging. Marshall: You said that you wanted to know. Ted: I didn't want to know! Marshall: You said you wanted to know! Ted: Well, I didn't know I didn't want to know! You knew. And you know me. And you should have known I didn't want to know! You know?
