I weaken all men for hours each day.
I show you strange visions while you are away.
I take you by night, by day take you back,
None suffer to have me, but do from my lack.
What am I?
The barber of Seville shaves all menliving in Seville.
No man living in Seville is allowed to shave himself.
The barber lives in Seville.
Who then shaves the barber of Seville?
