This group of friends takes their bets very seriously. For example, Barney had to wear one unfortunate garment for a whole year after losing a bet! Do you remember what it was?

In the aptly-named episode, "Ducky Tie", Barney bets Marshall that he can do the Shinjitsu techniques. If he succeeds, he gets to touch Lily's boobs, and if he fails, he has to wear Marshall's ducky tie for a full year. I think you know what happened.
