Next time you go for a stroll along the Appian Way, take a pair of shears with you. Then, if you happen to encounter a hairy slave hurrying along, you can seize him and chop off his hair with the shears. When his bare scalp is revealed you will be able to read the secret message tattooed upon his bonce, previously hidden by his luxuriant bouffant. The message will be intended for a distant military general or potentate. Commit it to memory. You are now in possession of important and privileged information, and knowledge is power.
