Give Me 50!

This afternoon four of my classmates were told "Give Me 50!" at the beginning of an afternoon class session. The instructor relented somewhat and said they could do the 50 pushups in two sets of 25. The offense? The instructor said she would tell us her first name at the party at the end of class. The four guys pushing the earth down tried to figure out her first name by questioning the other instructor. Speculation about her name pretty much stopped after that.
