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.

Get the Alabama pi mug.
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.
