Karma: ­Barney can’t stop thinking about Quinn and is surprised to find her at The Lusty Leopard where she works as a stripper. Quinn goes on to play him multiple times over the course of days, and gets a lot of money out of him in tips. He finally realizes that she is manipulating him and feels he is getting his pay back for the way he has treated women in the past. He runs into her at a coffee shop and after spending some time together and talking, he knows he has met his match. Meanwhile Ted is doing all he can to distract himself from the sadness of Robin moving out and trying to make use of her empty room. At the same time Robin is staying on Long Island with Marshall and Lily and they are trying to convert her into a suburbanite. In the end they admit they hate it there, and thought if she would stay it would make it bearable, and Ted decides it is time to move out and on with his life and gives his apartment to Marshall and Lily, and turns what was Robin’s room into their baby’s room.
