height in inches (i.e. 70 instead of 5'10") divided by the age you started puberty.

blacks and italians can add between 1/2 and 3/4 inch, while asians can subtract between 3/4 and an inch.

so far, its been close, if not exactly on par with everyone tested.

The Penis Size Calculator is 90-100% accurate.

seville calculator 

A myth by glasgow Rangers fans that the world media had a agenda against them.
While the world media reported the amount of Celtic fans as between 60,000 to 80,000 Rangers fans still insist they were no more than 30,000.
They also believe than the awarding of the World and European Fair play awards to Celtic fans only happened because of the biggest cover up ever in history in the history of mankind.

In a rangers pub you might hear "Them and their seville calculator ,I remember going to ibrox in the early 80,s I was one of the 5,000 loyal fans.
The problem is you hear that from almost every rangers fan over 40 and realistically you would need some kind of super seville calculator to figure that one out.
