A tiny tease about a man so greedy he bites bits from plates and gobbles the dates off a calendar. The pun on "dates" is the whole joke, and it lands well read with a straight face before the punchline breaks it.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
The greedy man is he who sits
And bites bits out of plates,
Or else takes up an almanac
And gobbles all the dates.
