Could any of the Danish posters shed a little light on the origin of this? It looks like it is from a sketch comedy show.
It's from the weekly Danish sketch show, 'Live fra Bremen', which is the Danish answer to the American sketch show 'Saturday Night Live'.
'Live fra Bremen' has made several sketches about Caro.
If you search YouTube for 'Live fra Bremen Wozniacki', then you will find other sketches too, like these:
Translation of the above sketch about the Haiti earthquake:
Q: Caroline Wozniacki can we get a comment on Haiti?
CW: Haiti, she's a great player but I'm sure I can beat her. I just need to get into the court and play my game.
Q: No, I'm thinking of Haiti the earthquake.
CW: No I don't know her, but I'm sure if I just play my game...
Q: No no stop stop, I would like a comment on Haiti.
CW: Oh, you should have just said that. [turns to the Camera] Hi, my name is Caroline Wozniacki and when I'm in Denmark I always listen to Radio Haiti.
Q: No no no, it's not Radio Haiti, it's a country.
CW: A country? How cool, then I can also call it from my [turns to the Camera] Sony Ericsson mobile.
Q: Listen now, 150.000 people died, don't you have any comment on this?
CW: Oh, then we must hope they had their [turns to the Camera] Europćiske travel insurance. Yeah, thanks.
Q: Tell me, don't you have any feelings at all?
CW: ... I have fucked Laudrup's son.
