Back in '70's when National Lampoon was the cutting-edge humour mag on the newstands (back before the The Onion and the Web), Rick Meyerowitz and Henry Beard dreamed up "The Dodosaurs". Many VP's of a certain vintage will have their 1983 book of the same name still on their bookshelves, although probably crushed to the back or living with the dust bunnies in an old box of unpacked books.
This is a later revisit to that concept that I found in the back of an old file I was throwing out. Really, it was funny at the time....
