As we've reminded everyone, April 17 (Tuesday) is the deadline for filing federal income tax returns. It's also the deadline for filing income tax returns in most states. Our friend Alan Greenblatt tells about something he finds surprising:

Lottery officials in Illinois say the third of the three winning tickets in last month's record $656 million Mega Millions jackpot has been turned in.
