The famous Uffizi houses a concentrated
treasure trove of paintings (over 1,700 works,
fortunately not all are on display at once), arranged in
a basically chronological order.
We had been warned about outrageously
long lines, but by happy chance when we arrived
there was barely any wait (a tribute to travel in the off-season!).
Within ten minutes we had entered the bookstore
and purchased our tickets. There was another wait, about
15 minutes, at the foot of the stairs. They allow
only 700 art lovers in the galleries at any one time,
but soon we were admitted past the velvet rope and bounding
up the grand stairway.
Up and up and up we went, until red-faced
and gasping we reached the top. The guard near the stylus
looked at our tickets, shook his head, and said grimly "These
tickets are-a no good."
"What? But we just bought them downstairs
a minute ago!"
"I'm-a sorry, but they are-a no good.
You will have to go back down stairs."
We stood there for a moment in silence, until
I finally caught something in his face. "He's
pulling our leg!" I announced, handing him
my ticket.
Found out, he laughed at his joke
as he tore our tickets and let us through.

Venus
and Cupid
Alessandro Allori (1535-1607)
Notice the pair of doves in the lower right, echoing the
main figures.
