a) On one occasion, Erdös met a mathematician and asked him where he was
from. "Vancouver," the mathematician replied. "Oh, then you must know my
good friend Elliot Mendelson," Erdös said.
The reply was "I
am your good friend Elliot Mendelson."
b) He had the habbit of phoning
fellow mathematicians over the whole world, no matter what time it was. He
remembered the number of every mathematician, but did not know anybody's first name. The only person he called by his Christian name was Tom
Trotter, whom he called Bill.
c)
This one's definitely a fabricated urban legend, but what the hell :-). There was a storm with thunder and lightening. Little Paul Erdos was in
bed, frightened and fretting and his mother couldn't calm him. Then, as
mothers seem to instinctively do, she found the right words.
"It's all right dear", she said, stroking his shiny head,
"there's always a prime between n and 2n".
After that, little Paul drifted off into a blissful sleep.

This is a story that I remember reading in E. T. Bell's excellent book 'Men of Mathematics'This story is about the number 2^67-1, the 67th
Mersenne number (Numbers, Mersenne had claimed to be prime, which was proven to be non-prime in 1903
by
Frank N. Cole (1861-1927). In the October meeting of the American Mathematical Society (AMS), Cole announced
a talk "On the Factorisation of Large Numbers".
He walked up to the blackboard without saying a word, calculated by hand
the value of 2^67, carefully subtracted 1. Then he multiplied two numbers(which were 193707721 and 761838257287). Both results written on the
blackboard were equal. Cole silently walked back to his seat, and this is
said to be the first and only talk held during an AMS meeting where the
audience applauded. There were no questions.
It took Cole about 3 years,
each sunday, to find this factorisation, according to what he said.
6. The mathematician
G. H. Hardy was to give a keynote speech at a conference.
Asked for an advance summary, he said he would present a proof of the
Rieman zeta hypothesis -- but they should keep it under their hats. When he
arrived, though, he spoke on a much more prosaic topic. Afterwards the
conference organizers asked why he said he'd talk about the theorem and then didn't. He replied this was his standard practice, just in case he
was killed on the way to the conference.
It was part of his tactics against God - in that he thought God would not
allow him to die on the sea trip, because then everyone would think that
Hardy had solved this great theorem. Hardy had other anti-God tactics,
including always taking an umbrella, and some grading or other boring work,
with him to the cricket games. For an athiest Hardy certainly spent a lot
of effort against God.
Apparently Hardy's ambitions were:
