Have you noticed fake pee in the ad?

It's nice to be a Neighbour

Yesterday I took a closer look at a billboard advertising entertainment show It’s nice to be a Neighbour. And from the distance it looked well crafted ad, however standing right next to it revealed a big mistake. I was surprized that the agency who did this was so sloppy! The dog’s pee on the floor looks totally fake (photoshoped on the ad). And why? Because they didn’t erase the pee where the wood is vertical.
