Has someone dropped it?
Listen Action Man. Have you never dropped one in the loo?
The only steps I and my former colleagues ever took with regards to devices, whether suspect or not, was feckin big ones - backwards. That's why nearly all of us are still here today.
And you never ever cut the red one, not until you nearly cut the green one and, at the very last nanosecond, change you mind.
Best thing to do if you discover a bomb is to stop what you are doing immediately, slowly reach down and behind you, lift a handfull of cack and gently cover the detonator with it.
How do I know there will be cack behind me I hear you ask.
Don't worry, there will and plenty of it.
Sorry to make light of a very important issue.
I shall not comment on this matter again.
