Ted: What should I do? I should totally go down there, right?
Lily: Don't interfere. Some guy is expecting to marry this woman on Saturday.
Ted: Yeah, an 8.5 guy. Look, if I was marrying the wrong person and the right person was out there and knew it, I'd want that person to come down to my dermatology office and tell me so. In that scenario, I'm not interfering, I'm a happy ending.
Barney: [chuckles] Happy ending.
