I went all pit-a-pat when Barney told Robin she's the (second) most awesome person he has ever known. As soon as she whispered in his ear I knew she was gonna show him the video (which, btw, wow -- "If you re-edit it, there's a tampon commercial in there.") so I was not expecting them to hook up. I am pleased that they did, though.
P.S. JAMES VAN DER BEEK played Simon.
