The Sheep are Calling

I'm willing to bet you haven't seen this before: Yeah, that's right. Sheep made out of telephones.
I wonder if they are fully functioning- I'm not saying I'd get a telephone sheep (Hello, Habitat? Are you selling telephone sheep yet?), they are pretty big, but I'm not ruling it out, either. I love how the hooves are made out of receivers!
