Blue Eyes.

I recently fostered a rescue dog that was...um...unique. He was mostly or all blue Australian cattledog, with blue eyes. This gave him a permanent case of crazy eyes.

Fortunately he was also a wonderfully well-behaved dog, to the point of being boring sometimes. We got tons of applications for him and he went to his new home within a couple of weeks. This freed me from my obligation to provide the rescue with "better" pictures of him...
