All the idiots and the geniuses and the hucksters and the naifs

Dinarchus, lawcourt speeches, In Defense of Euthygenes, only surviving fragment (F20):

"The whole place was open."

I badly want this one sentence to have been the entire defense speech, ideally for burglary. It doesn't quite beat the guy who begins with 'Okay, so I didn't read the contract...', but it's along the same lines.

Ah, humanity. Never change.
