Question 956

X is a U.S. citizen and holds a Ph.D., in computer science. He graduated first in his class of seven million at 'Caltech' — Calcutta Technical Institute — going on to earn his doctorate at the Y Heights Institute of Technology. X began working at the Z during his college years to pay off his student loan, but stayed afterward as he had come to enjoy his job and the friends he had made. He remained an illegal immigrant until the Mayor of Y proposed a municipal law to expel all undocumented aliens. X responded by purchasing a forged birth certificate from the Y Mafia that listed his parents as U.S. citizens Herb and Judy Nahasapeemapetilon, but when he realized he was forsaking his origins, he abandoned this plan and instead successfully managed to pass his citizenship test with help from the most famous residents of Y. Thus, he refers to himself as a "semi-legal immigrant".
X, Y and Z?
Answer: X: Apu Nahasapeemapetilon, Y: Springfield, Z: Kwik-e-Mart.
