Actually, your tinfoil hat wasn't effective in the first place...for it to function as a Faraday Cage, it has to complete enclose your body, or at least be grounded...otherwise it will only amplify the signals...
*sigh* I as well, but I'm never on late on weekend nights anymore cause I'm busy lately... :D luckily, in the summer, I can stay on as late as I feel like every night. That'll be sweet. ^^
