Borrowed from a post the

"8.01 exams are coming up this week, and we'd like to remind you of a message that your GRTs passed on to you last year banning "showering". Some freshmen might not have heard of "showering" yet, but there has been some tradition around MIT, on the eve of the first 8.01 exam, of "putting" freshmen in the showers. Although in general this was viewed as a fun event, in many cases the freshmen reported being intimidated and sometimes even physically hurt. In those cases, "showering" becomes just a form of hazing. For this reason, the Dean of Student Life, Larry Benedict, issued a ban on any "showering" activities last year. Such a ban was communicated through the GRTs to the students. Larry sent a very strong reminder this year with a STRICT BAN, which, if violated, could result in serious disciplinary action. The following 4 paragraphs are parts of Larry Benedict's message to us so that you fully understand the nature of the ban and the seriousness of violating this ban. We ask you to read it carefully and take it seriously.
'Let me remind you that showering is no longer permitted at MIT. At its worst, such behavior might be considered a violation of state criminal law. In addition, MIT has its own policy against hazing, as well as policies against assault, harassment and general disrespect of others.

I can't say I have any good input on that whole thing. Since I was bigger than most people there (and definitely meaner than most of them ;-) no one actually tried to "put" me in the showers like that. I know some of my friends went through that and some were amused by it and some were annoyed. I guess it's one of those weird social things that has pros and cons. I do think that it's unfortunate that things have gotten to the point where something that's supposed to be fun has become a possible criminal offense. Regardless of wether it got to that point because people started acting too viciously towards each other or because the administration decided to treat adult college students like children, it's still sad and kind of weird to see how different things have gotten to be over the years.
