[Harmless Teddy Bear]

The only Japanese men who do NOT beat their wives are the Samurai.

Not the only but yes a Samurai tended not to be foolish enough to beat his wife. His wife was usually the daughter of another Samurai and was trained to kill.

The threat of death tends to remind you to keep a lid on your temper.

I thought it might be because samaurai are more concerned with their young boy sex objects.
