There are two simili jokes in the poll.
The first is aimed at people who are studying science.
IUPAC= International Union of Pure and Applied Chemistry. I was just using the letters in a different fashion.
The second is merely the presence of the
PI in the Pirates part. I leave this one to wiki to explain...
Wiki
The mathematical constant π is an irrational real number, approximately equal to 3.14159, which is the ratio of a circle's circumference to its diameter in Euclidean geometry, and has many uses in mathematics, physics, and engineering. It is also known as Archimedes' constant (not to be confused with an Archimedes number) and as Ludolph's number.
There is also a little comedy in the fact that pirates are the missionaries of the all mighty
FSM (Flying Spaghetti Monster)And this concludes my little not so little explanation.
