LOL. I do know that, and I'm not sure if you are from the US, but here, when you use swear or otherwise use off color language, people often say "Pardon my French" not because it's French that they've used, but simply to note that they realize they've deviated from the accepted norm.

Also, while my daughter's got some kid-sized guitars for Christmas from their uncle, I've yet to see a guitar small enough to fit into a cajones....no matter how much of a BAD-ASS the dude thinks he is! lol
