just last year... there were a couple of them delivered to numerous
systems... they were not done on purpose, though... they were the result of
a faulty filesystem on the originating machine... i forget the size they
were on arrival but they unpacked to like 100x that... they arrived via a
route through several mail distribution hubs as they were echomail and
processed as echomail on systems with drive space large enough to handle
them...
