It looks like the animal revolution is widening and it's not just cows who are severing their ties to homo sapiens. Early today, a tractor-trailer filled with pigs overturned on a major highway near Little Rock, Arkansas. Some of the swine remained in the truck but others took advantage of the situation and left. Apparently, they hogged the road so much that commuters had to detour. The State Troopers tried to round up the escapees and that was no small job because the swine could weigh as much as 800 pounds each.
