A guy who had forgotten the dates for a number of his friends' and relatives' birthdays and anniversaries, decided to compile a list on the computer and have the dates highlighted on screen when the machine was turned on.
He went to a number of computer stores to find a software program that would do the job but had no luck at the first few. Finally, he found one where the clerk seemed experienced.
"Can you recommend something that will remind me of birthdays and anniversaries?" the guy asked.
"Have you tried a wife?" the clerk responded.

Direct-dial long distance calls

In 1951, direct-dial, coast-to-coast telephone service in North America began as Mayor M. Leslie Denning of Englewood, N.J. called Mayor Frank Osborn in Alameda, Calif. Three digits were added to the number dialled. They were able to begin taking just 18 sec. after the dialling. Previously, coast-to-coast calls were placed by long-distance operators. Since the 1930s some calls could be dialed between cities and towns with relatively small areas. By 1965, 9 out of 10 telephones used the new service, with millions of users connecting through thousands of new generation switching centers, with a numbering plan that could be applied nationwide, and a billing system that could record and process millions of transactions automatically.
