Spies' Biggest Secret Weapon (Hint: Below the Belt)

Semen Invisible Ink
This book is all kinds of perverted.
Don’t judge a book by its cover. Seriously.
According to a new boring-looking tome published in the UK, M16: The History of the Secret Intelligence Service 1909-1949, British spies found that spoo made a fabulous invisible ink during World War I.
Sheesh. This takes the sexy sheen off of the latest sexy spy scandal. This fun fact only serves to raise all kinds of other questions.


For instance, how did this discovery come about? What other fluids did they test? How did the invisible ink become visible at the other end? And most importantly … what the hell?!
Apparently, invisible ink becomes visible after you use a “developing agent.” This can be heat, chemical, or light. I’m guessing, since I watch too much CSI, that the third option was the one used in this case, but I’m open to other interpretations.
There are certain other gross facts associated with this discovery:

  • The guy who spearheaded this research was named Mansfield Cumming. (Snk!)
  • The agent who had actually figured it out had to be moved to a different department because (duh) everyone made fun of him.
  • Spies were instructed to only use fresh “supplies” because otherwise, the ink was detectable via a rancid aroma.

All together now: EEEEEYUW!!!
