Really, can sheep swim?

Spotted this at a swim meet this morning. Janie h. knits, a local knitting store, has bought advertising on the wall of the Perth community pool. Unlike every other local business (of which there are a dozen or more) alongside it, Janie h. has customized her ad for its location: swimsheep

That's right. It's a smiling sheep, doing the front crawl. On a sign about four feet high and at least six feet long.

I originally thought this was aspirational advertising, since sheep obviously couldn't swim, what with their hooves and soggy woolen coat.

"As God is my witness, I thought sheep couldn't swim."
