In Purple Giraffe, Ted runs to meet Robin at a location where she is reporting and informs her that he is throwing a party. He holds it repeatedly when she says that she is unable to come and she only manages to come when he holds the party for a third successive night.
At the party, Barney picks a girl who doesn't know anyone else, she just says she works with a guy named Carlos (who no one else seems to know). Later, when Robin inadvertently finds out that the parties were held for her, Ted covers it up by lying and saying that he wanted her to meet another guy, who turns out to be Carlos.
At the end of the night, the entire gang is at the bar, talking and getting to know Robin. Also at the bar is Carlos, and the girl Barney hooks up with making out.
