Umm...just lemme see if I have this right: "You're the daddy 'cos after my one-night stand with you a year and a half ago I haven't slept with anyone since - BUT I'M NOT OBSESSED WITH YOU OR ANYTHING!"

I can see 3 possible explanations for this (well, if it was real anyway):
1: She's lying and
is obsessed with her nameless paramour.
2: She's lying and little August could well be someone else's kid.
3: She was actually a wayward nun

who hooked up with the random tourist

during an alcohol-fuelled one-day stint out of the cloister

after drinking too much communion wine and/or watching
Sister Act

one time too many, and returned the next day racked with guilt for her sindiscretion. 9 months later along came little August, and sadly that 'immaculate conception' routine just doesn't wash anymore.
Not so effective IMO, I'd rather my casual holiday one-night-stands with pretty women who don't remember my name or nationality
didn't result in little 'surprises' down the track, even if I'm not being blamed etc - I'm just not cut out for fatherhood. Doesn't exactly send a great message about Denmark's safe sex practices - ever hear of birth control, Karen? I thought Europe was pretty big on effective sex ed. For brand recognition maybe they should have stuck to pushing Denmark's proud history of political cartoons.
On the plus side, it does make for a great advertising slogan.
Denmark: Come for the easy women, stay for the unwanted pregnancy!
