Now I'm gonna teach you how the crow flies...

Here's a great song (really two songs) about a jacknife, an ear, a crow, and a red newt:

Michael Hurley, Unholy Moral Rounders, Jeffrey Frederick & The Clamtones – Jacknife/The Red Newt (buy album)

If you like it (or are at least intrigued by it), then you should check out the album from which it comes, called Have Moicy!, by Michael Hurley, Unholy Moral Rounders, Jeffrey Frederick & The Clamtones. This truly brilliant album from 1976 also features the song, Griselda, which was later covered by Yo La Tengo.
