PROBLEM: Richard Castle:  Now , there are seven ranch hands that fit the bill of tall , dark , and handsome . But in order to find out which _ one _ was fooling around with Whitney , we have to first determine who of them are married . That means we need to go on a wedding ring search , and these are the possibilities . So I split their classes up between us .
Kate Beckett: Whoa ! Hold up . Harmonica for Beginners , Cowboy Saloon . How come you get all the cool activities ? And I get Hog Tying ?
Richard Castle: Because this was my idea . Though it will be a shame that we 're spending the first day of our honeymoon apart .
