An eggcorn sighting: check out the number of Google hits for the word "grueways", all in the context of a song from The Sound of Music that frequently appears on lyrics websites as:
You are 16 going on 17In brief, this is a mistaken transcription of "roués" (listen at 0:47 in the above video). What makes it an eggcorn, and interesting, is that it's not merely an error, but transforms an unknown word into something semantically meaningful for the context: in this case, presumably the idea that it refers to some kind of gruesome creepy person or monster. You certainly wouldn't want to run into a "grueway" on a dark night.
Fellows will fall in line
Eager young lads
And grueways and cads
Will offer you food and wine
This illustrates one of the downsides of the ease of propagation of Internet material: like quotation websites, music lyric websites copy promiscuously and indiscriminately from each other, and wrong lyrics spread very rapidly without much mechanism for error correction.
