PARIS: Ten generations of Gellers have gone to Harvard. I have to go to Harvard.
According to Paris, the Geller family have been attending Harvard University since the 18th century. This doesn’t seem possible, as the Gellers are Jewish, and at that time Jews weren’t permitted to attend Harvard (and tended to be excluded from higher education, and many other institutions). The first Jewish student at Harvard in 1720 had to convert to Christianity, and still wasn’t really accepted. Even in the twentieth century, there were heavy restrictions on Jews attending Harvard.
It is possible that Paris is lying in a desperate attempt to persuade Rory that she “deserves” to go to Harvard more than Rory does. Of course later on Paris and Rory do attend the same university together.
