A dwarf is passing out somewhere in Detroit!
A man from AI walked across the mountains to SAIL to see the Master,
Knuth. When he arrived, the Master was nowhere to be found. "Where is the
wise one named Knuth?" he asked a passing student.
"Ah," said the student, "you have not heard. He has gone on a
pilgrimage across the mountains to the temple of AI to seek out new
disciples."
Hearing this, the man was Enlightened.
Q: What do you call the money you pay to the government when
you ride into the country on the back of an elephant?
A: A howdah duty.
