Responding to pressure from religious groups, Alabama's state legislature redefined the value of pi from 3.14159 to 3 in order to bring it in line with Biblical precepts.
Sure, its a myth, but if it were to happen anywhere it would be Alabama.
"cornbread are square; pi are round"
The number 3.
Using the number 3 instead of the real value for pi because you are no better at math than the average redneck.
A hoax news article posted on the Internet saying that Alabama was changing the value of pi to 3. Many people believed that Alabama would actually do this.
I just did some real quick calculations in my head using Alabama pi.
