How about taking back a selection of canes - yes, the ones the locals use to discipline their children...!
My friends are amused and astonished to hear how common it is in Singapore that so many Singaporeans cane their kids (this is still done in schools here and still encouraged by the powers that be). We went out for dinner one night with a Singaporean manager whom my spouse was working with and he proudly exclaimed that he didn't believe in caning children until they were at least 2 (yes, two) years old as otherwise they wouldn't understand...
I once ripped out a page a few months ago from the Straits Times where a doctor and his wife were talking about their family life and that they "didn't use the cane much" on their daughters. My friend in the US asked to keep it and it is now pinned to her fridge door....when her kids are playing up she points to the ST report lol!

(Come to think of it, there was another one in the Sunday Times a few days ago...will rip that out too).
Most HDB estates sell canes...they have colourful 'umbrella' type plastic handles at the end and they cost approx 50c-60c. I'm taking some back to the States with me to show my friends.
