If rice cooker, goodness knows how many rice cookers the couple
will end up with after the wedding. 
Aiyo, Unker Charlie, guess you not yet marry hor, usually after
marriage, the couple will go into a storm, fighting and quarrelling
before coming to norm, so during these period, you give them
cookers and cheaper stuff for them to throw. Then 7 or 10 years
later, when they celebrate their 7 years itchy marriage
anniversary, (if their game didn't end by then), you then give them
gold, silver or even diamonds.
