When cool weather hits, sheep get frisky. Some sheep have a deep need to show everyone else who is top dog.. er, sheep. Here we see Jethro letting Samson have it. Fortunately, he didn't turn his wrath on Israel or Tommy, because they would not have fared well. Four-horned sheep are not nearly as successful in a tussle as two-horned ones. You can easily see why. However, just because they aren't contenders, doesn't mean they can't stand around with mob mentality and watch the show. Silly sheep.
I also need to mention that no sheep were harmed during this short altercation. All four sheep are back to being quiet pasture mates. I'm so glad they can eventually work out their differences without any bloodshed. So far.
