Boxing Ladies

After a recent visit to my active 88-year-old father-in-law's care center (where he's recovering from a broken leg and eager to get back to doing yard work), we exited through the lobby. To our surprise, we discovered two ladies watching mixed martial arts on TV. Not only were their eyes trained on the screen as two guys grappled and kicked and blacked each other's eyes, but one lady had her hand raised in a fist. This element of surprise is perfect for a story plot, and leads to much speculation, such as: were these two women the Number Girls for early boxing matches, carrying signs for which round it was in skimpy bathing suits? Did they have brothers or husbands who boxed or wrestled? Were they female wrestlers in their day?
What do you think?
