If you want to play with the hardware...
Have a momentary start push button that triggers a mosfet to start the PIC. When the PIC starts a pin will keep the mosfet triggered. To kill the PIC another momentary push button will break the gate signal to the mosfet.

WHILE
the start push button his held "down" to start the PIC it also brings another pin HIGH.
RANDOM X
WEND
GOTO MAIN PROG

Kinda sounds like something Goldberg would do
