I was on vacation in Rome and we went to the Vaticsn museum to see the Sistine Chapel.
There was the magnificent golden orb, surrounded by a small chain fence, in the courtyard there. When me and my then girlfriend got there, there was also a choir singing some beautiful hymn.
But it gets better.
Turns out, this giant 12-15 foot in diameter art sculpture spins! And, would luck have it, there was a really bored security officer in duty. I asked if we could touch it, and he said sure. Then he smiled and told my girlfriend that he thinks it might spin, and we could try if we wanted.
We get right over the fence and this tour guide comes running over and and yells and us, but then the guard comes over and just tells them to stop, and they do.
