Yule Lad #5 Pot Scraper or Pot Licker

He sneaks into your house and steals your dirty pots and pans.  He then scrapes and licks them of their food...

Pot Scraper, the fifth one,
was a funny sort of chap.
When kids were given scrapings,
he'd come to the door and tap.
And they would rush to see
if there really was a guest.
Then he hurried to the pot and had a scrapingfest.[1]
