One of the funnier "hey, he's following us!" incidents that I know of happened two years ago to a friend of mine. He, his two sons (19 and 23) and two buddies had spent the morning hunting on their lease an hour or so out of town. When they drove back home for lunch, they encountered one of the local idiots who tried to pass them on a "no-passing" stretch of road, with oncoming traffic. He wasn't successful, but seemed rather annoyed that they hadn't pulled off the road onto the shoulder to let him get by. For the next ten to fifteen miles, he alternately roared up to their rear bumper, threatening to ram, with his brights on, or pulled next to them, shaking his fist and screaming epithets.
Eventually, my friend decided that enough was enough, and pulled off the road onto the verge. His tormentor pulled off ahead of them, and jumped out of his truck, screaming threats about what he was going to do to them, etc., etc. My friend simply asked his sons to retrieve everybody's (unloaded) hunting rifles from the rear of the SUV, and by the time this moron got out of his pickup and turned to look, there were five men standing in a row next to the SUV, each one carrying a rifle (pointed safely up in the air, of course).
Apparently the twerp got that "deer-in-the-headlights" look, stood dazed for a minute, then jumped back into his pickup and took off like he was running from the Devil himself. My buddy called the cops and advised them of his behavior, and they later arrested him for meth abuse (he had paraphernalia visible in the truck when they stopped him). The cops were hugely amused... they told my friend that the perp kept muttering to himself in his cell, something about "They've all got guns! They've
all got
guns! They've
ALL got
GUNS!!"
