Star Trek fans, here is the best parody:http://archive.org/details/StarWreckInThePirkining
“The future looks bleak for Captain Pirk. Originally from the far future, he traveled back to save the world, but was shipwrecked on the 21st century. The world of the past is a dangerous place and he is finding it difficult to convince the ladies he is, in fact, an intergalactic space hero from the future. To make things right Pirk comes up with a questionable plan to save mankind’s future...”
Funny and amazingly good effects too.
