Spontaneous Generations

Here's a very cool page of random generators, mostly for RPG-related stuff (e.g. character names, kinds of weapons, random spellbook titles, you name it). The Miscellaneous page is the best, though. Some cool examples:

Random B-Move titles:

The Sleepover of Sexy Pain
The Vengeance of Saturn
Dark Grave Robbers
The Mansion of the Beautiful Skydivers
The Torture of London

A random villanous plot:

Your fiendish plot: create a magical focus, easily allowing you to kidnap a movie star for a huge ransom, easily allowing you to live in luxury!

Some random action movie trailer tags:

In a dark kingdom, in a time of necromancy and danger, two kitsunes try to find a mystic artifact and battle lawlessness.

In a galaxy of technology, a relic hunter and a spy quest for fame.

In a universe of corruption and lost souls, in a time of monsters, eight dancers try to prevent the destruction of mankind.

In a wicked city, six conjurers seek love.

On a forbidden planet, four rangers and a space pirate search for a lost artifact.

(Actually, you know, that one about the dancers sounded kind of interesting...)
