When he awoke, the doctor was nowhere in sight. But clearly someone had been by, since there was a folded piece of notebook paper in his lap.

“…a poem?”

Let me tell you the story of one Etaoin Shrdlu
Not a normal man like me or a normal man like you.
He was only present as a mistake some people made
Until it happened once too much and Etaoin up and stayed.
The printer was astonished and dropped his coffee cup
When Etaoin walked right in and asked him what was up.

It was signed, or perhaps titled, simply Shardborn.
