The sale took place after the father spent two weeks searching for the video game for the Nintendo Wii gameboard.

"So I was so relieved in that I had finally got the Holy Grail of Christmas presents pretty much just in the nick of time. I couldn't wait to spread the jubilance to my son," the father wrote on the eBay website.

"Then, yesterday, I came home from work early and what do I find? My innocent little boy smoking pot in the back yard with two of his delinquent friends."

The man, a school teacher, who kept his identity private, said he sold the coveted video game to punish his son and discourage him from smoking dope.

The sale was a boon for the family's bank account, since the game the father purchased for $US90 was finally sold to an Australian who plunked down $US9,100 for it.

The naughty son, however, will not go without a present on Christmas.

"I am still considering getting him a game for his Nintendo. Maybe something like Barbie as the Island Princess or Dancing with the Stars ... I know he will just love them," the father said, tongue-in-cheek.
