Chinese Business Trip
A man went on a business trip to China and wanted to buy some gifts for his kids. He went to a shop and found a nice looking CD player. Wary of buying inferior goods, he asked the shopkeeper, 'What would happened if this does not work?'
The shopkeeper quietly points to the only sign in English that reads, 'GUARANTEE NO SPOILT'.
Feeling assured, he paid for the CD player and returns to his hotel. He tried to use the CD player after returning to the hotel but it would not even switch on.
