A little lady from Wisconsin had worked around family dairy farms since she was old enough to walk -- with hours of hard work and little compensation.
When canned Carnation Milk became available in grocery stores (1940s or 50's?), she read an advertisement offering $5,000 for the best rhyme beginning with "Carnation Milk is best of all..." She said, "I know all about milk and dairy farms, I can do this!"
She sent in her entry and about a week later, a black limo drove up in front of her house. A man got out and said, "Carnation LOVED your entry so much; we're here to award you $1000, even though we will not be able to use it..."
Here is her entry:

Carnation milk is best of all,
no tits to pull, no shit to haul,
no buckets to wash, no hay to pitch,
just poke a hole in the son-of-a-bitch.
