It puzzled me when I saw the picture, but I did know that a Claymore is a sword, a brutal thing that you certainly don't want to encounter, so I guessed that it was a military device. I Googled Claymore bomb and learned that it was a lethal anti-personnel mine. Reading it's description I thought it was well named. A perverse sense of humour.Cool. Now all I have to do is spend $200-$300 to have a trailer hitch that doesn't exist installed on my itsy bitsy Chevy Cruze and I'll be all set for the gag 99% of southern Californians won't get.
