First up we have the 1956 classic, The Mole People. An insightful tale of English professors, archaeologists, monsters and the whitest folks on Earth...or in this case, in the Earth.

Then we have my contribution to the 2008 Christmas in July Roundtable (http://www.geocities.com/darksider66/julyxmas2008.html), Silent Night Deadly Night, a heartwarming tale of a traumatized youth who believes that he is Santa Claus...and that it is Santa's duty to punish naughty people by sticking sharp things in their bodies.
