Fark (of course) yesterday linked up news of one of the earliest representations of a phallus yet discovered:

A sculpted and polished phallus found in a German cave is among the earliest representations of male sexuality ever uncovered, researchers say.

The 20cm-long, 3cm-wide stone object, which is dated to be about 28,000 years old, was buried in the famous Hohle Fels Cave near Ulm in the Swabian Jura.

It was apparently used to nap flint, so it's either got heavy religious connotations or represents the workings of a really bored tool maker.
