Spock, we have an emergency. Someone has activated the self-destruct sequence. If we don’t act quickly the whole ship will blow up. We have less than ten minutes.
Perfect timing, Captain. Starfleet just e-mailed us the new codes to de-activate the self-destruct sequence. I have my code right here on my computer. Do you have YOUR code? We both have to enter our codes for de-activation.
NEW codes? I haven’t checked my e-mail in months.
