Unnamed Characters(Bug-eyed monster)
Bug-eyed monster is an early convention of the science fiction genre. Extraterrestrials in science fiction of the 1930s were often described (or pictured on covers of pulp magazines) as grotesque creatures with huge, oversized or compound eyes and a lust for women, blood and general destruction. The term is now often abbreviated to BEM.
"We hitched a lift," said Ford.
"Excuse me?" said Arthur. "Are you trying to tell me that we just stuck out our thumbs and some green bug-eyed monster stuck his head out and said, 'Hi fellas, hop right in. I can take you as far as the Basingstoke roundabout'?"
"Well," said Ford, "the Thumb's an electronic sub-etha signalling device, the roundabout's at Barnard's Star six light years away, but otherwise, that's more or less right."
"And the bug-eyed monster?"
"Is green, yes."
