I bet a fun thing would be to go way back in time to where there was going to be an eclipse and tell the cave men, "If I have come to destroy you, may the sun be blotted out from the sky." Just then the eclipse would start, and they'd probably try to kill you or something, but then you could explain about the rotation of the moon and all, and everyone would get a good laugh.
