This is the recipe from the infamous urban legend of the person who supposedly asked Mrs. Fields/Neiman Marcus/insert-place-of-choice-here if they could have the recipe for their cookies, were told "of course, but unfortunately we are required to charge two fifty for it", and then when the credit card statement came in, it was $250, not $2.50 (and so, claims the "recipient", they decided to share the recipe far and wide, usually in the form of spam!)

However, it makes fantastic cookies. The iteration below is my own, shamelessly based on the copy which I found at Tane' Tachyon's website; her version, along with her commentary, can be found at http://www.armory.com/~tachyon/recipes.html#ulcookie

Cream: 

     2 cups butter or margarine (1 pound) 
     2 cups white sugar 
     2 cups brown sugar 
     1 tsp. salt 
     2 tsp. vanilla 

Then mix in one by one 

     4 eggs 

Then mix in 

     4 cups flour 
     2 tsp. baking soda 
     2 tsp. baking powder

And then 

     5 cups "blended" oatmeal (process 5 cups of oatmeal, regular
     or quick cooking, in your food processor or blender until the
     consistency of course flour)

And then 

     1 12 ounce bag semi-sweet chocolate chips 
     1 12 ounce bag semi-sweet chocolate chunks (or use another back of chips)
     1 12 ounce bag milk chocolate chips      
     3 cups chopped pecans or walnuts


Roll into golf-ball-sized balls (or use ice cream scoop) and bake for around
10 minutes at 375. They will be browned but still soft inside. 


Note:  You can also substitute brickle chips or peanut butter chips for
the nuts or some of the other chips.
