This is my favorite new word, I don't understand the etymology (monde=world, "green world"??) but I didn't know there was a word for this concept until my hubby (N) told me today. Here are some links to funny sites that collect examples:
"All Time Funniest 100 Lyrics" at KissThisGuy.com (homonym for "kiss the sky" as in " 'scuse me while I..." in Jimi Hendrix's "Purple Haze")
"The Misheard Lyrics Hall of Fame"
