I love the "law for you'uns and a law for we'uns" quote. I think Ma was one of the most interesting characters to appear on Bonanza (not realistic, but interesting).
Ajax

I think this is one of the best episodes in the entire series--beautiful acting by David Canary and Lorne Greene.

Ajax

This is one of my favorite episodes, although it has some of the most "non-favorite" bits in it. I just can't believe Hoss would turn so violent against Adam without first giving him a chance to explain--this SO out of character. Then when Ben & Joe walk in and try to stop the fight, Adam jerks away...
