Years ago I had my horses boarded on pasture near Lyons, Colorado. There were maybe 15-20 horses total, including my three. It was a particularly cold winter and I was out feeding grain every evening. There was one huge black horse of some indeterminate draft breed that had been there so long that no one, including the land owners, seemed to have any idea who he belonged to. He was pretty gregarious and always hung around when I went out to feed. On one particular evening, I had just set a full bottle of beer down on the tailgate of my truck and walked away with a feed bucket, when the big black horse ran up and snagged the beer bottle. He trotted off with it in his mouth, and I heard ominous sounds of crunching glass. I got pretty nervous when I couldn't find any broken glass on the ground, so I ran and got the owner. We summoned the vet who administered a dose of mineral oil by tube to the stomach, to ease the passage of whatever he had managed to ingest. The old horse didn't seem any the worse for wear, so we turned him loose. He must have been a little ticked off over the whole procedure, because he walked over to the vet's brand new truck, took a bite out of his tail light and ran off. I alway left my beer in the cab of the truck after that.
