It seemed like a good idea at the time

I guess everyone needs a rap sheet. If you can't get it for something fun like murder or rape or harrasment or purgery there is just one thing left to do....heave a pig over a hotel counter.
I especially like the cop comment..."It might be a redneck thing". Let me provide an alternate interpretation; it might be a stupid thing. Seriously, how does that mental conversation go:
"Hey, me & the guys need some sort of contest. But they have all been done...we have already had the lawnmower races, speed sitting contest, watermelon catapault launchings...we need something to top that...but what....hey, Charlotte's Web is in theatres, we could throw a pig over a hotel counter! YES! We have a winner!"
It had to be something like that if, in fact, as stated, there was no alcohol involved. I can only imagine what they would have come up with if there had been...maybe putting clothes on the pigs prior to the preeminent pork prank proceeded.
