* The computers in the Duke Cave has a damn accurate boot bios screen, resembling those of an Award BIOS boot PC.

* Behind the set of the "Damn It's Late Show" there's a stage hand getting berated by an angry actor for walking across the stage during filming, a parody of Creator/ChristianBale's infamous rant on the set of ''{{Terminator}} Salvation''. Duke can even punch him out:
