My family would know it was the lottery

So the guy who won the $220 million Powerball lottery (translating to a lump-sum payment of about $80 million after taxes) over Memorial Day weekend did not tell his family until last week:

"Duke said he told his father and sister about the jackpot but the rest of his family was unaware until Sunday, when he asked them to meet him in Sun Valley. He said they had assumed he was going to reveal a terminal illness, multilevel marketing scheme or a wedding engagement."

If I summoned my family to Sun Valley, they (optimists all) would expect the lottery news and suspect the terminal illness, but I fervently hope that multilevel marketing would not enter their thinking.
