There is some humorous graffiti in the latrine at Ostia Antica (pictured in the article). The Seven Sages of Greece had permeated the collective consciousness to such an extent in Rome that some unknown individual inscribed some graffiti referencing some of them.

For example, one graffito reads: "Ut bene cacaret, ventrum palpavit Solon," which translates to "To shit well, Solon rubbed his belly."

Another says, "Durum cacantes monuit ut nitant Thales," which translates to, "Thales admonished those shitting to strain hard."

Another: "Vissire tacite Chilon docuit subdolus", or "Sly Chilon taught to fart silently."

To get the modern cultural connotation, substitute "Thales" or "Solon" for "Einstein" or "Abraham Lincoln".

Some of the other graffiti do not reference the Seven Sages. The Seven Sages graffiti use a higher register --- past tense and a meter associated with comedies. But the other graffiti are in a lower register --- present tense and no meter. One of these others recommends "shake yourself about so you'll go faster."

One of these also references the tersorium, or sponge on a stick, that the article discusses. (Also called a xylospongium.) The graffito reads "No one talks to you much, Priscianus, until you use the sponge on a stick."
