Those from nine to fourteen years of age became water boys.

More often, however, they were treated like the water boys on the football team.

Now we know what the players do in the huddle when the water boy comes running out with a bucket.

He eventually volunteered to be the team's water boy.

"Isn't there some way you can dress me up as a water boy or something, so I can help?"

It amused Chloe to make a water boy out of learned man.

His first job was as a water boy on a road construction crew for 15 cents an hour.

"I get kids volunteering to be water boys and years later they make the team."

He felt like the water boy to the football players.

It was the water boy, and it hadn't even been much of an error.
