They're made out of meat

I’m a big fan of science fiction writing, and with humor it’s even better! Here’s a great one I found online, first a note from the author Terry Bisson, “I’m honored that this often shows up on the internet. Here’s the correct version, as published in Omni, 1990. Thanks for your interest in my work. If you enjoyed this little piece, please give a dollar to a homeless person.”
