When does a chip become a coin?

ANSWER:

At midnight on the last autumnal equinox preceding
leapyear. This phenomenon takes place at precisely
the same time; everywhere, but it only lasts for a
very short period of time. The experience is quite
enjoyable when shared with a member of the opposite
sex who enjoys chipastronomy. Check your calendar,
as the transformation period is less than 36-hours
away and last for approx. 9-seconds.
