 Robin invites everybody to a banquet and Ted is insecure about bringing a date or not. Barney hooks him up with a girl that seems to be a prostitute while Robin brings a real date. Ted pretends to be cool with the fact that Robin has moved on, but Robin s date is her sleazy colleague Sandy Rivers whom Ted and Marshall constantly make jokes about when watching him on TV. With all these people in the same room, the evening seems to be getting interesting.
