Strange Tales #98

An alien lands on Earth and issues a challenge to best any man at any contest or the Earth will be invaded. The alien defeats all comers until one man challenges it to sleep longer than him, claiming to have slept for one million years. The alien vows to sleep for two million years. Guards are set up around the cave to keep anyone from disturbing the creature and the man's formerly nagging wife is eternally grateful to him for saving Earth.
