Music video with a mannequin in it?

About a year ago, I saw a music video featuring a guy singing and playing guitar with a mannequin dressed like a girl. He took her to the park and slid down the slide with her and then, I think, went into a cafe where he saw another woman dressed like his mannequin girl with a male mannequin who was dressed like him. They got together and left their mannequins behind. Does anyone recognize this?

I know the video you are talking about... I just can't think of the name...
