“There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.”

Who fancied an anthropoid ravish;
In his haste for the rape
He grabbed the wrong ape
And the anthropoid ravished Mctavish.
