What was the last internet scam, you heard??

i heard of this one Email forward claims that would-be robbers are trying to gain access to victim's houses by tricking them into smelling a candle that contains a substance that will render them unconscious.

The last time i heard about the internet scam was when one of my friend came with big smile that he had won a lottery online of million dollar and that they have also sent him a certificate to house to claim his prize. I laughed at him of his not knowing about these type of scams. I also told him that i used to receive around 10 mails daily similar to this and then only he realized that he had not indeed won any prize. If i had not warned him of that, i am sure that he would have been scammed easily and he would have sent them money somewhere down the line. With people like him around only, those scam sites are still operating with full gains and cheating innocent people.
