Before y'all write in with advice...
I have a cunning plan.
Don't tell me you're not gripped.
This reminds me of those childhood games where you are, for example, trapped in a steel crate deep underwater with only a welding torch, a snorkel and a giant bathplug to help you out.
Something to do with the Beano and a Mr. I-Spy?
Cunning? Did I say cunning?
More cunning than (in the Blackadder vein) a Very Cunning Thing Indeed.
