What's in a Name, Knocker-Upper

There were a lot of ways to wake up before the alarm clock was invented. People living in towns had chimes from the church bells, and people living on farms had roosters to crow them awake. In some places, people made getting up in the morning a much stranger experience.
Native Americans would make sure they got up early by drinking as much water as physically possible before falling asleep. That way, the water would fill up their bladders while they were sleeping. Pretty soon, they would be so full that they needed to get up. So they would get up early.

In England, you could pay a “knocker-upper” to get you up in the morning. Your knocker-upper would come to your house first thing in the morning and bang on your window with a long stick. If he wanted to make his shilling, he would keep banging until you got up and shared with him the money (about 12 pence) and customary curse words of morning.
