A great book to read is called
Wrongs of Passage. It lists thinks you couldn't even imagine! I also read a book, I forget the exact name of it, but it tells stories of WWII recruits and the bootcamp stuff they did, similair to fraternity hazing (without the drunk active creativity) and that hardships bring people together. I know for a fact that almost all southern chapters of any fraternity haze and I know it unites not only the pledge class, but each pledge to the active chapter because everbody goes through the same ordeals.
My favorite hazing story is on my friends dad told me about from the 60's called "Little Buddy". During his hell week the pledges were told to go and buy little squids (small enough to fit into a condom). They then had to put the squid into a condom, and onto their dick and wear it for a week. Pretty damn gross if you ask me, but damn funny.
