This is a trick question, because in the world as we know it, entropy never decreases, since the chance of this happening approaches and infinitely small fraction.
To answer the question though:
Take any closed system of events that you've observed, and rewind the events as if you were "going back in time".
Example: An egg the has splattered all of a sudden recombines off the floor and becomes a whole egg again.
Some scientists believe that the last time entropy ever decreased in our universe was right before the big bang. Since this chance occurrence, entropy throughout the whole universe has been steadily increasing.
My addition (person 2) - However, entropy CAN decrease locally, just not universally. Essentially entropy rests on the fact that work ultimately comes from a flow of heat energy from high to low, eventually balancing out. Once all the heat energy is uniform in the universe, we will experience "heat death" at which point no work will be able to be done. However, in systems WITHIN the closed system of the universe, entropy CAN be decreased. Freezing an ice cube, if you follow the entropy equation which I don't have with me, is one example of this. The cost of this local decrease in entropy is a universal increase in entropy from the heat released that is greater than the local decrease in entropy, thus the second law is not violated. Another example is biological growth. We humans develop from a single cell into a vastly complex arrangement of cells, but at the same time we produce heat that increases universal entropy more than our bodies decrease it.

What is percent decrease of a to b?
To determine a percentage decrease, ascertain the actual decrease, then divide this by the base number and multiply the result by 100. Decrease = a - b The base number (the number on which the decrease is based) = a Therefore, the percentage decrease = 100 x (a - b)/a % EXAMPLE : What is the percentage decrease of 15 to 11. Decrease = 15 - 11 = 4 : Base number = 15 Percentage decrease = 100 x 4/15 = 262/3 or 26.67%
