Porky was eighteen years old, friendly, and eager to do things right. Unfortunately, he wasn't especially bright. He had just started his first job, as a delivery boy and general 'go-fer' at a furniture warehouse. His first task was to go out for coffee. He walked into a nearby coffee shop carrying a large thermos. When the counterman finally noticed him, he held up the thermos.

"Is this big enough to hold six cups of coffee?" he said.

The counterman looked at the thermos, hesitated for a few seconds, then finally said, "Yeah. It looks like about six cups to me."

"Good," Porky said. "Give me two regular, two black, and two decaf."
