Lotto Mistake

I went to cash my lotto receipt in at the post office. I told him I had five numbers that matched. After a few minutes of inspection he replied, "Bu shi, ni you liu ge haoma." I grabbed his hand excitedly, "Zhenda?!" I had six numbers instead of five. I won NT10,000 not 4 (a little over $300usd). This week hasn't been too bad.
