From the Futurama episode A Taste of Freedom (season 5 episode4) :
Did the Decapodians have a secret anti-perspective weapon or maybe a shrink ray is involved?
In this cross-section, the DOOP's (Democratic Order of Planets) Nimbus appears to have 14 levels.
Here, the same section of the Nimbus as seen just before it crashes to Earth with cloud of smoke after having apparently shrunk to the size of a Central Park tree (well, the size of the canopy of a Central Park tree). All the while, buildings with fewer than 14 stories loom in the background.
