This little creep made me laugh half an hour when I came upon it. It’s a doormat with a subliminal message. Well not really subliminal. Just put it on your doorstep with the “Come in” part showing to the visitors. They’ll come, see the doormat, think “Aah, what a cute doormat” and proceed at entering. Not knowing what awaits them upon leaving. They’ll get dressed, open the door and in the minute they want to exit, you ask them something they have to think about. They throw their look on the floor before them, and see the cute doormat. Except that its message has changed. Well, it’s really not so complicated, you could just tell them “look what a cute doormat I’ve bought” and it’s pretty much the same. You’ll laugh half an hour, like me. Just make sure you tell them when they come, not before they leave.
Did I mention you can also wipe your footwear on it? That is if you don’t want to ruin a wonderful piece of both graphic and comedy art.
