I don't think I have ever seen spam with this characteristic.
FWIW, here's some statistics for those who are wondering. These are
grepped out of the last week or so of the spam-list mailing list. More
information at <http://www.spam-archive.org/>

Those marked with a "*" are based on additional heuristics, such as a
certain amount of "ugly words" in the header, or being from a
"suspect" domain, etc.
The spam-list spam is obviously only representative for the spam that
people who feed the list are receiving. (If you don't presently feed
the list, please consider signing up. There's no need to receive
anything, but you help people for whom receiving others' spam is
important.)
