How I Met Your Mother: Showdown

Lily and Marshall decide to live apart for the two weeks before their wedding to prove that they are not co-dependent, but they can't do it and sneak out to meet at a hotel each night. Meanwhile, Barney is excited about his upcoming appearance on "The Price is Right" because he believes that Bob Barker is his father. He goes on the show and wins big, but doesn't tell Bob Barker that Bob is his dad, because he's afraid it might not be true.
