MOUNT LAUREL, N.J. — Twelve Princeton University students were taken to a hospital for drinking too much during an initiation weekend for off-campus eating clubs that have a history of overserving alcohol.

University spokeswoman Emily Aronson said Monday that the number of alcohol-related hospitalizations between Friday and Monday was higher than it has been for past initiations, but she couldn't say how much higher because school officials were still reviewing past years' data.

She also said that the university was still sorting out how many of the students attended parties at off-campus eating clubs, which were holding recruiting and initiation events they call "bickering" over the weekend.

One of the clubs held a toga party after a screening of the movie "Animal House."

The Ivy League university is full of unique rituals — and the 10 eating clubs are among them.
