Being watched

I saw the espionage team thats been tracking me again, they don't know I'm on to them, but well, they'll have a nasty surprise when they look for me to leave the house, I've got plans to use a smoke screen and a couple of mirrors to send them barking up the wrong tree, I also reswept the house for bugs, haven't found anything, but i'm sure they're listening in somehow, I'm going to make a foil hat to intterrupt their brain rays, then they wont be able to read my mind...
