And you know, just for laughs I'd like to see Barney having cute daughter... or even daughter-twins! :D That's would be very fun, because of all this womanizing staff in the past)) and he would be totally in love his daughters)) Somebody please stop me!!!))) Oh dreams, dreams!
Not straight up... but I think that after a while, in a few years time they might. Seeing as it was revealed that Barney wants kids when he was dating Nora. And Robin's character has grown so much past the kid-hating commitment phobe she used to be.
It may take a while, but I think it will happen. :) I'd love to see BR have hot twin daughters and Barney fighting off all the guys that are like he used to be.
