The Bad Guys (curse them!) have begun communicating in lolcats, to enable their Internet communications to take place unnoticed.
This is a job for the NSA/GCHQ crack team of cryptanalysts.
Unfortunately they're a bit busy today, so you'll have to do it.
A secret message is concealed in the lolcatstream above.
It's a pencil-and-paper cipher. You do not need a computer to decipher it.
All the information you need is above the horizontal line. These instructions (everything below the horizontal line) do not contain hidden information.
From HUMINT assets, you have received the Bad Guys' code book. You know for certain that the message above consists entirely of one of the following code words:
YODA (meaning "Your cover has been blown!")
LUKE (meaning "Get me Tom Cruise's autograph!")
LEIA (meaning "Explode the enormous bomb on Tuesday!")
FISHCAKE (meaning "Send more food!)
DURANCE (meaning "Give yourself up to the police!")
Summary (just for clarity). There is a hidden message in the lolcats above. It consists of one of this set of words: YODA, LUKE, LEIA, FISHCAKE, DURANCE. Your task is to discover which of those words the message consists of. Please explain your answer.
It's been a few days and nobody's cracked it, so here's a clue (if you need it):
Cats like bacon.
