Mares eat oats and does eat oats and little lambs eat ivy. A kid'll eat ivy, too. Wouldn't you?Is a prime example, though nonsense. The term Mondegreen comes from Percy's Reliques:
...[From] part of a popular nonsense song of 1943 called "Mairzy Doats"--per ASCAP Hit Tunes booklet, written by Milton Drake, Al Hoffman,and Jerry Livingston. The beginning is more or less rendered:
Mairzy doats and doazy doats, and little lamzi tivy. A kiddely tivy too, Wood'n you?
Ye Highlands and ye Lowlands,Where the final line is actually "And laid him on the green."
Oh, where hae ye been?
They hae slain the Earl Amurray, [sic]
And Lady Mondegreen.
