One day a lady walks into a bar and asks:-I would like a coffee, not too hot, not too cold but just right. - The waiter serves it to him. The second day it is history repeating itself and continues so for a week, the last day the lady again asked the waiter:-I want a coffee, not too hot, not too cold but just right ... - And the waiter is not too happy:-dear lady, she has broken, not too high, not too low but just right!! -
