The false fraternity Pi Tau Zeta, on the
second floor of the West Parallel of East Campus (better known as Fred the Dorm) at
MIT. Historically, Second West was one of the last
all-male halls in East Campus, and they renamed themselves
as a pun off of the Yiddish meaning. Today, PTZ is co-ed, one of the more active halls
in intramural activities, and notorious for their inflatable body parts displayed during Rush.
