Pecking Order

In the days when an earth closet in the backyard shed, served as a toilet, my Grandfather complained privately to my Grandmother, that when he had sat down to accomplish large affairs, he had experienced a pain in the scrotum.
No other members of this family, consisting of women and a young man, had a similar experience.
In due course, it was discovered that a hen had made a nest on a ledge behind the thunderbox. Grandfather, suffering the effects of age and gravity, was the only one to fall within the range of the sitting bird.
