QC FYI: Brits Used Semen To Help Win World War One

June 1915. England finds itself locked in a brutal battle against the Germans. Mansfield Cumming, the first chief of Britain’s Secret Intelligence Service had to discover an invisible ink for sneaking messages across enemy lines. Tormented, he struggled to find a solution until he came upon one… or rather, one came upon him—male semen!
Yes, not only is male semen great for cooking it also makes a darned good invisible ink because it doesn’t reveal itself under iodine vapors or other common detection methods. But even though the army had no shortage of this ‘ink’, the brilliant solution ran into several problems:

However, the discovery also led to some further problems, with the agent who had identified the novel use having to be moved from his department after becoming the butt of jokes. In addition, at least one agent had to be reminded to use only fresh supplies of the ‘ink’ when correspondents began noticing an unusual smell.

We wonder how many British soldiers splattered ‘secret messages’ onto stationery and left them to moulder in the trenches. Did any gay German soldiers detect these notes by smelling the faint hint of boy batter? Do secret agents still send top secret cum stains? Would James Bond?
