Sheeps is not sheep

I have a feeling that many people have seen the banners while on-line that say something to the effect of  "Shot the            and get a free iPod." I just hate those banners. Well I just a few minutes ago came across the most idiotic, the most illiterate, the most...ok I think you get the picture. It said "shoot the sheeps and get a free iPod." When I saw that, I was both annoyed and doing my best not to laugh my head off.
