Despite the title, this thread is PG-13, and does need to be kept family-friendly. It's a take-off on the old Jeff Foxworthy routine '...you might be a redneck.'
The rules are simple:
1) Any post made must end with the phrase 'it might not be PG-13' or a reasonably close variant.
2) Posts should be no more than a sentence or two.
3) The post should describe a situation in which the thing talked about might not be PG-13.
4) Have fun!
As an example:
If your post looks like it was written by Samuel L. Jackson ... it might not be PG-13.
