Thanks for the advice there, European Trailer Trash. You may have to improvise your tinfoil hat. Form a sheet to your head and then put your hat on to hold it in place.
You've got a point about the insidious Zionist sneaking around in the shrubbery outside the kitchen though. It's too cold to wear the full body tinfoil suit all the time, but I have had good luck removing the shrubbery and installing a watch-dog.
This being America, I'm also heavily armed, which they seem to respect. If something (other than the dog, that is,) moves out where the shrubs used to be, I just pump a couple of 12 gauge shells in that direction.
There is a hidden benefit to this. I no longer get door-to-door salesmen or religious proselytizers. Of course, my inlaws no longer drop by either. Oh well, I guess you can't have everything.
