What episode does barney first and সেকেন্ড চুম্বন robin?

Well, if memory serves correctly, the first time was the end of "Sandcastles in the Sand" and the সেকেন্ড was not until "The Leap." The first was আরো spontaneous, and afterwards, Barney spent the entire fourth season in প্রণয় 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.
