I'm surprised no one has mentioned Frederick Silver's "The Twelve Days After Christmas", which is (however amusing) a real downer for most of the birds involved, not to mention the pear tree. I first learned this in a seventh grade chorus class, and eventually tracked down a recording which remains on my phone to this day.

There are several recordings on YouTube - it turns out to be a popular concert choir number (and to my mild astonishment, has been cheerfully performed by the Mormon Tabernacle Choir). That said, this one strikes me as possibly the cleverest. I should note that unlike most of the YouTube versions, the one I bought personally features a male singer, and references one of the maids a-milking rather than a drummer.
