we are moving!

Marcello [at the Stratusphere, who was exhausted from International travel from Brazil]: ….The lights, the balcony, the city outside…everything is moving at this place. I don’t understand it.
Renee: Marcello, I think you may be tired but could figure it out if you thought about it.
Marcello: But even the lights on the ceiling are going around all funny. [Marcello thinks about it] Oh, oh! I see…we are moving!
Renee: Very good!
