Awww com'on Jerry. You know as well as I do that you remove as much as you  
want until you break one, then add a little. Yours will break at 35g's and mine 
 at 25 g's. Which is adequate?
 
I won't charge $100K. 
 
That'll be Fifty thousand follars please (VBG)

ball of butter as big as a walnut'.
