What episode does barney first and سیکنڈ kiss robin?

Well, if memory serves correctly, the first time was the end of "Sandcastles in the Sand" and the سیکنڈ was not until "The Leap." The first was مزید spontaneous, and afterwards, Barney spent the entire fourth season in love with Robin. Then in the season four finale, they realized they both had feelings for each other and kissed again, then decided to work out their issues later.
