Pig smiles

One of the pigs mudded himself up in an almost exact half mud, half clean split.  Brown/pink.  The pigs are growing slowly but steadily.  They are thick and strong enough now to be a little scary, and I don't go in their pen anymore.  If I do I get enthusiastically leaned on and greeted with a vigorous head rub, which I'm afraid any day now will knock me over.They're always into a good neck scratching or behind-the-ears rub, though.
