a DYN I haven't noticed posted.

When the mutants show Fry & co around, they open the door to the atomic bomb which is the EXACTLY like the set from Beneath the Planet of the Apes. . . "Smithers, have the Rolling Stones killed." "But sir, that's not..." "Do as I say!"

Considering this was alluded to in the dialog, I wouldn't call it very subtle. :)

But yes, that's where the reference came from.
