Morning people are evil robots in disguise
You know how in movies, people always wake up by snapping open their eyes and leaping out of bed? That just ain't right. People who do that are actually evil robots like the Terminator (as played by Arnold “It's not a tumor” Schwarzenegger). Humans wake up slowly, and stumble around until they get their coffee - or until noon, whichever comes first.
Check your friends. Check yourself. Evil robots are everywhere.
