A spoof Trivago advert showing two people in the throes of passionate sex has gone viral.
The 10-second clip shows two randy lovers "testing out the bed" through a hotel room window with the light clearly turned on.
In the background, a group of men, who are filming the x-rated clip from the other side of the road, can be heard giggling.
The room next door features a man gazing out of the window, alone, presumably wondering where all that noise is coming from.
