En mulig forklaring på et merkelig bilde

Det merkelige bildet til høyre en fra en side med følgende tekst:

OK, I really don't get this sign from the Riverdale Farm... We didn't stick around long enough to figure it out, either.

First there is a pig cut in half. But there is also some guy bowing over to the pig. He's got some round drips coming out of his stomach. He may be missing one of his legs. And there seems to be bullet holes over his head.

Kan en mulig forklaring være at round drips coming out of his stomach rett og slett er et gjerde? (Ikke så lett å tegne et gjerde rett fra siden.) Altså en advarsel mot å mate grisene
