From my frosh year trials, these were the seniors. They decided to dress as dead famous people. This is Annie, Jill, and Lynn as the Three Stooges. And an example of the sophomore role, as intimidator. The sophomores had decided to be the mafia.
Every dorm takes different themes for their trials.
These are just examples from my experience. One of the most visible parts of Hell Week is the stage in the main dining hall where frosh put on various performances at the request of their hellers. This was me and Rosy pretending to be badass after one such performance. This is the group of people responsible for Hell Week in Pem East during Hell Week of 1997. Several of us were sophomore reps, the ones officially in charge of the hell week for the dorm.
