It's nice to have dirty examples.

Wait for it.  I've seen this:

HTTP/1.1 200 OK
Content-Type: text/html
Content-Length: 12345
CP="FOO BAR WIBBLE STUFF": CP="FOO BAR WIBBLE STUFF"

The CP= string is the right hand side of a P3P header, but I've seen
it duplicated as the header name and value, complete with quote
characters and spaces in some responses from sites running IIS.  It
was about 5 years ago; I'm reconstructing this from memory.  I don't
remember which site, but it wasn't an obscure one.
