It's easier to like some people the less you know about them. Bowel movements fall into the "way too damn much information about anyone" category.
BMs are just the vehicle....
This is a
Tale-teller's Tale!!
You can't believe the twists and turns that come about.... it has you in stitches of laughter at one point, only to be taken aback by the next zany happenstance to occur.... our protagonist is never short on resourcefulness as he plods from one hilarious event to the next.... and his loving wife, the heroine of the story, is admirable in her dedication....
In short, it is classic American modern literature..... not that many here care about that.....
