[Greifenklaue]

...The PCs are honorable stuffed animals in a hole in the ground who, with toilet plungers, fight robots (which, for budgetary reasons, are indistinguishable from humans) for fame and glory but it all turns out to be just a hoax.

... The PCs are singing lawyers in a world gone mad who, with just a pinch of salt, fight off unwanted advances for what is right during the Great Depression.

...The PCs are naked thugs of unknown origin who, with ray guns, fight KHAAANNNN! for sweetmeats until everything abruptly and inexplicably stops.

The PCs are mythical lads and lasses out on a date who, with guns (and more guns), fight illiteracy for the Eye of Vecna. Soon to be a major motion picture! <- my favourite!!
