Other than hoping Stephanie Kramer would catfight someone on 'Hunter', or the Jenna Wade and Pam Ewing would escalate beyond verbal bickering on 'Dallas', or that Christie Brinkley's Sports Illustrated swimsuit issues would include a beach catfight with another model, mine was IRL, not via media.
The IRL was at neighborhood cul de sac co-ed touch football. Two attractive neighborhood 'good girls' who I looked up to had a chippy Saturday afternoon game one time, slapping each others' hand off of each other after plays, and giving each other dirty looks.
Finally, as one long pass play went way downfield, the two good girls lingered back at the line of scrimmage in an angry staredown. Suddenly, they lunged at each other with fists and feet, trying to destroy each other. The tore at each others's hair and faces for over 5 minutes. I thought about it all weekend, and at a neighborhood sleepover, another girl told me they were dating the same guy.
