Hey-Oh!!

The roundest knight at King Arthur's was Sir Cumference... He ate too much Pi.

3.14159 times too much pie.

In ancient China, values for π included 3.1547 (around 1 AD), √10 (100 AD, approximately 3.1623), and
142/45 (3rd century, approximately 3.1556). Around 265 AD, the Wei Kingdom mathematician Liu Hui created a polygon-based iterative algorithm and used it with a 3,072-sided polygon to obtain a value of π of 3.1416. Liu later invented a faster method of calculating π and obtained a value of 3.14 with a 96-sided polygon, by taking advantage of the fact that the differences in area of successive polygons form a geometric series with a factor of 4. The Chinese mathematician Zu Chongzhi, around 480 AD, calculated that π ≈ 355/113 (a fraction that goes by the name Milü in Chinese), using Liu Hui's algorithm applied to a 12,288-sided polygon. With a correct value for its seven first decimal digits, this value of 3.141592920... remained the most accurate approximation of π available for the next 800 years.
Sorry for the "n" - couldn't get the commodore 64 to give me the proper symbol for pi - hah!

What about the Einstein-Pi(e) connection?

Einstein figured out that gravity is best described by a field theory rather than as a direct interaction between individual bodies,
and connecting fields to localized bodies involves integrating over the surface of a sphere, and the area of a sphere is proportional to Pi.

The whole birthday thing is just a happy accident.
