There is a joke about a Nigerian lady married to a Chinese guy against her relations’ wish. The couple’s first child died at infancy and her relations were expectedly heartbroken and at the same time suspecting a foul play. Her older sister cried a bucket at the couple’s home and kept shouting “I know, I know”. Other relations quickly gathered around her, in the assumption that she had found the truth. When pressed to divulge what she knew, she said “I know. Chinese products don’t last”.
