I demonstrated how to do a stationary leap and land on the ground today as I was teaching pep squad their competition jazz dance. Some of the girls were being SO lazy and would jump about 2 centimeters off the ground and just crouch down instead of actually going to the floor. Ugh. I was so irritated that I turned around and said, "Excuse me. I just did it full out and I'm pregnant. If I can do it I'm pretty sure you can do it too."
It worked! No more lazy freshmen.
