Analysis of Dependable Wake-up-er

Some persons waken at the noise
   Of newsboys bringing papers;
Others hear alarming clocks,
   Or careless milkmen's capers.

I'm told few wake to honeyed calls,
   As loved ones' voices coo;
And many heed the barnyard fowl's
   Gay "cock-a-doodle-doo!"

Are you aroused by singing birds,
   In near-by trees, each morning;
Or: "Hey! get up--or you'll be late!"
   Or some such pleasant warning?

Though many wake-up systems thrive,
   I'd recommend to you
As most reliable of all,
   A baby's loud "boo-hoo!"
