I think colleague Natedog was implying a pun, saying there is a literal and a proverbial pig in the aforementioned picture. You see… there is a woman of substandard and porcine qualities, holding an actual pig. So basically (pay attention to this bit) you could say… there are two pigs, in said picture.

The lesson in basic English was quite unneeded, and quite honestly no one could give a fuck if it was.
