When I was in high school, spikes were in fashion and at that time, I had 
a vacation job of waxing floors at the local schools.  I could always 
tell if a woman or man taught in the room as there would be half-moon 
marks, especially under the desk, in the rooms where women taught as they 
would dig in their heels when they backed the chair away from the desk.  
The same would be true in front of the chalkboard.  I remember reading 
that a 120 lb woman would exert the equivalent of 20,000 lbs of force on 
the floor when they walked in spikes.

This story is great to illustrate forces or impulse with students.  The 
moral is, never allow a woman in spikes to walk across your hardwood floors.
