Haiku / Anachronism Stew

Something's not quite right.
Ninjas in Ancient Egypt?
You fail history.

What did you just say?
The Nazis have invaded? !
Release the T. Rex.

Huh? I don't recall
There being dinosaurs when
World War 1 was fought.
The Dread Gazebo

Cavemen using nukes
To fight the robot army
In World War Two? Sure.
