"hass-ee-deem"-it's Hebrew) are an orthodox Jewish sect. The jokes
above refer to various further subsects and their peculiarities. The
Lubavitchers, the most prevalent, are known for their belief that the
Mossiach (Messiah) will be coming along soon. The Bratzlaver joke
refers to the fact that they all revered their founder, the Rabbi
Nachman, and since he died they haven't really replaced him, as
nobody in the group feels capable of filling his shoes. The Satmar
are very strict in their adherence to the sex-role distinctions
prescribed by the Bible-in one area, they've been fighting with local
authorities about school busing, because they believe that women
should not be allowed to drive, and the school system employs a lot
of women as bus drivers.
