Lots of good responses given by earlier commentators, but maybe it would be useful to find out why the lady got PO'd. I suspect that she heard the lyrics from the "adult" part of her head and focused on the literal meaning. A "child", big or small, wouldn't be so literal, but would be far more likely to laugh at the sheer preposterousness of the images. Teens, however, being the weird creatures that only they can be, might find yet some other interpretive device.

You could probably turn the offended "adult" into an ally if you sincerely thanked her for pointing out a view that hadn't occured to your inner child (innocent as we all know it is), and then adjusting the lyrics to something even goofier from a kid's perspective, but less violent from her adult view.

It's also quite possible that the complainant is an utter ass beyond responding to the milk of human kindness, in which case some deservedly rude rejoinder might be more appropriate.

For myself, I don't think I'd get my knickers in a wad over what is legitimately a "gray zone" dispute.

We'll still love ya no matter how you resolve the conflict.

Slan!
