OK, two new limericks have been sent out via email - with the filenames 'smoking' and 'gun'
The first limerick, if you take the first letter from each line you get 'dutch', and the second, a fancy name for cats is felines.
Pancito over at unfiction then discovered this site: www.metacafe.com/channels/dutch.felines/
(there is also a YouTube channel - www.youtube.com/dutchfelines)
which features only this video:
Unknown Paranormal Creature - Weird Military - Chupacabra - For more of the funniest videos, click here
Creepy, but there doesn't seem to be any clues to glean from it.
