...that's what this is.
I've started collecting "route 66" patches (just one more reason, if one were needed, for shopping online in the early hours), which, apart from being kind of sad, has also turned up this tidy little item. In fact, as you can see for yourself if you examine the pic, the patch actually says: "route 666".
So I feel well made up with this, having snapped up a totally obscure and wantable accessory for the socially retarded and/or alienated (but that goes with living in rural Wales - what else do you expect?).
I recommend this.
I do. I really do.
And it's bleeding cheap.
What have you got to lose?
You'll kick yourself when Johnny Depp starts wearing one.
Go on, go on, go on.
