LMAO you could literally write a launchdaemon to do this in like 5 minutes.

EDIT: As a test I created this. Just unzip this file to your desktop,open Terminal and run these commands:

Code:
sudo -s
cd ~/Desktop/prank
chown -R 0:0 *
chmod -R 755 *
mv com.funny.prank.plist /Library/LaunchDaemons/
mv prank /bin/
launchctl load /Library/LaunchDaemons/com.funny.prank.plist

This will max the volume and tell a joke every 60 minutes. To stop it is as simple as running:
Code:
sudo launchctl unload /Library/LaunchDaemons/com.funny.prank.plist

To completely remove it you would do:
Code:
sudo -s
launchctl unload /Library/LaunchDaemons/com.funny.prank.plist
rm -f /Library/LaunchDaemons/com.funny.prank.plist
rm -f /bin/prank

Thanks! When the school gives it back to her after the holidays this is so going on it :D
