George is half full

George was a pirate, but he wasn’t a very good pirate.
When asked if a glass was half-empty or half-full, George picked up the glass and drank it.
“It’s empty now,” said George. “Can I have more water?”
The psychologist running the experiment told George that wasn’t the point, and he refilled the glass halfway again.
George picked it up again and drank it.
“Thank you,” said George. “But wouldn’t it be easier if you just gave me a full glass of water?”
“It might spill,” said the psychologist.
“Oh, okay,” said George. “Can I have my five bucks now?”
