Here is a paragraph of words in the public domain: He put the good old cup of tea softly on the table by my bed, and I took a refreshing sip. Just right, as usual. Not too hot, not too sweet, not to weak, not too strong, not too much milk, and not a drop spilled in the saucer. A most amazing cove, Jeeves. So dashed competent in every respect. I've said it before, and I'll say it again. I mean to say, take just one small instance. Every other valet I've ever had used to barge into my room in the morning while I was still asleep, causing much misery: but Jeeves seems to know when I'm awake by a sort of telepathy. He always floats in with the cup exactly two minutes after I come to life. Makes a deuce of a lot of difference to a fellow's day.

The above paragraph was from "The Inimitable Jeeves" by P.G. Wodehouse. That was written in 1923, when people were named Jeeves.
