How I Met Your Mother Episode 5.17 Of Course

After Robin interviews Anita, the author of a dating book "Of Course You're Still Single, Take a Look at Yourself You Dumb Slut," she arranges for her to seduce Barney to get back at him for his insensitivity to her after their break up. Following her own guidelines Anita will not sleep with Barney until the 17th date. Due to Barney's frustration Ted constructs a "superdate" guaranteed to melt any girl. Perpetuated by Robin's anger that Barney never took her on a date like this when they were dating, she admits that his blatant philandering has been painful for her, and she can't move on with her co-anchor Don as a result. Barney realizes what he is done and to make it up to Robin he promises he will not sleep with Anita, who of course, is all over him now that he is rejecting her. In addition, he turns over his "superdate" plans to Robin who goes with Don and has an amazing time.
