Isn't It Ironic?

Our apartment managers have posted signs all around our complex. It is a heavy laminated sign of a girl, walking her dog. The dog is obviously trying to go to the bathroom and the girl is holding a pooper-scooper under its bum. The sign reads:

Someone is walking their dog inside the complex and not picking up after it. Please pick up after your dog when walking it inside or outside the complex. Be considerate of others. Some don't like to see it, smell it, or step in it.

Thank you,

The Management.

This has been staked in the grass out front. I was walking my dog, he went up to the sign, sniffed it, promptly lifted up his leg and went to the bathroom all over the sign.

Ironic?
