The most obvious ritual to perform on a lottery ticket is to fill out the form on the back of the ticket. People do this because they are afraid of winning, and then not being able to write the information down, and somebody else might take their ticket. This is a very bad idea. You might as well rip your ticket in half, because if you write your name on it, you will not match a single number. Besides, what if you only won three dollars (the smallest prize)? Do you want the guy at the convenience store to think that you actually thought that was worth signing your name for?
