Shower
Couple of random thoughts:
How do you think the peakholes were made in the first place? My theory is either it was an artitectual mistake and that was stumbed upon by a student, or maybe the guys who were building the school had younger brothers going there and decided to give them something they would enjoy, and set it up for them.
Also do you think this group was the first group to know about it, or was it a tradition like the book in American Pie that kept getting passed down year after year.
Finally, do you realize how big of a disaster this would be for a school district if this happend now. Every girl who had taken a shower in that lockerroom since whenever the holes were put in would be able to sue the the school for sexual harrassment. I guarentee the principal would not have been laughing if he was staring down the barrell of the biggest lawsuit ever filed againist a school.
