Hey Bear....I would agree with rin753. I remember seeing that Lucy episode, and I remember thinking at the time, it was pure comedy. It would be interesting who actually came up with that idea. One of the writers I suppose. In any event, I think it was done for laughs, although I do remember getting somewhat excited because you knew a fight was coming. The two women kept going back and forth and you just knew it was going to happen. But it was more funny than arousing, at least to me.
And Tony, the movie clip you posted was excellent. I had seen that quite a while ago. The movie title escapes me, but the way the fight was done was pretty realistic. The two women were not experienced fighters, and went at each other in a good old fashioned catball catfight.
One other point to rin753's comments; even today catfights are thought of as funny by everyone who is not turned on by them. Check out the various YT posts, whereby two girls are really going at it, and you hear people, girls and boys, laughing. I don't see anything funny at all. To me it's very arousing, and not funny. But then again, as you point out, we're a very small minority.
