Do you know why Singapore Government banned chewing gums?? Please read below
for the answer.

One day Lee Kwan Yew went to Thailand and had lobster at the dinner with the
Thai King.  After Lee finished, he asked the King.

Lee :	Your Highness, what can you do with this lobster skin?
King:	We cannot do anything with it, we just throw away.
Lee :	Oh, no.  In our country, we send it to the factory and produce some
	prawn cracker.

Then Lee had an orange. After he finished, he asked the King.

Lee :	What can you do with the orange skin?
King:	We cannot do anything. We just throw away.
Lee :	Oh, no. In Singapore, we send it to the factory and produce some
	orange jam.

Then Lee asked for some chewing gum. After he finished, he put on the plate
and asked the King.

Lee :	What can you do with the chewing gum?
King:	Oh, no.  We just throw it away.
Lee :	In Singapore, we send it to the factory and produce condoms and send
	it to Thailand.

After the meal, just before Lee said good bye to the King, the King asked Lee.

King:	The technology in your country is highly admirable, Mr. Lee, but what
	can you do with the condom when you finish using it?
Lee :	We cannot do anything.  We throw it away.
King:	In Thailand, we send it to the factory to produce chewing gum and 
	send it back to Singapore!!

So that's the end of chewing gum in Singapore.
