Nice. It does end quite abruptly but I, unlike others it seems, caught the message. Don't dumb down your work to compensate for the lack of intelligence of others. Ignorant people obviously wouldn't see the humor in a message that they don't understand. Good work, as always.
P.S. At first I wondered why you didn't use a voice actor for the humans but as it went on, I can't say I understood relevance for that but I can say it fits.
