The U.K. is a little more "lax" in their advertisements.
Let's go to our very own irishthatcherite for verification.
I'm in the Republic of Ireland btw. lol But, we get the British TV channels over here. It's true to say both countries are fairly lax, not unusual for a person's bare arse cheeks to appear in an ad. Saying that, I have not seen this advert (trust me.. I would not miss seeing a nude woman.. lol), and while a certain degree of nudity is permitted in advertisements, I have yet to see an ad that shows or implies sexual activity like the above advert. Unless it's been shown on Sky, as I don't have Sky. Anyway, all Guinness ads at present are about the so-called up coming Arthur Day.
