  A young student had just miserably failed his introductory calculus
exam, something his roommate couldn't understand.
  "I thought you had that stuff down cold," he puzzled.  "What went
wrong?"
  "There wasn't a thing I could do," explained the washout.  "I was sitting
between identical twins."
  "So?"
  "I just couldn't differentiate between them!"


  An engineer boarding a flight to Amsterdam noticed that the
flight attendant was asking the passengers whether they were Polish.
Those who were got directed to seats on the left side of the airplane,
while the non-Polish were distributed everywhere else.  Having just
read his network news on the subject of ethnicity, the engineer
was brimming with self-righteousness and prepared to upbraid the
young attendant for her callous behaviour.
  "Look, I'm an engineer so I understand damn near everything, but
I can't see any possible justification for isolating Polish people
like this!"
  "Well," explained the attendant, "I didn't think I'd ever have to
tell an engineer that a system is unstable if it has Poles in the
right half-plane."
