Waaay back in the day, before alarm clocks were widely used, people like Mary Smith of Brenton Street in London, had the job of waking sleeping people early in the morning.
They were called Knocker-Uppers. Mrs. Smith shot dried peas into market workers' windows and was paid sixpence a week (about $.04 today).
