As Adam is about to get married to the beautiful and smart Sarah, his best man Bav is more nervous than him. They have been friends since they were four years old but Bav seems to have never grown up and is now a uniquely odd and needy individual, worried that, when his best friend goes off to form this new life with Sarah, he’ll be left high and dry. Bav messes up the ceremony, first accidentally knocking the priest into a lake, then giving a terrible best man speech. The only thing keeping Sarah from killing him is the fact that in a couple of days they will leave on honeymoon to Venice, getting away from him.
