Drive ‘em crazy with a Mind Molester. It will set you back 20 bucks and drive ‘em nuts with a loud chirping sound.
If the sound doesn’t drive them batty, wondering when or where the next chirping barrage will come from will. Link to the Mind Molester here.
I can think of a better way to drive someone bonkers. Have them listen to Billy Ray Cyrus sing Achy Breaky Heart over and over again.
