Check out the trailer of Star Wreck : In the Pirkinning!
 

www.starwreck.com

A must for every Star Trek universe fan - shameless spoofing and really bad-taste jokes. This is a Finnish production, the people involved are mostly students. The F/X are very good for a non-pro work, I definitely recommend checking the earlier movies too (I just don't know where they are ATM, they used to be available at the main site).

EDIT: The old movies are here: http://swreck.cust.magenta.net/oldies/
