Happy April Fools' Day!

Rest easy, that headline was just a joke. You still have 140 characters to compose a tweet. Believe it or not: The productivity of the newsroom took a hit to come up with that fake headline. A whole host of people across NPR contributed a bunch of ideas. These were our 20 runners-up:

The national championship game in men's college basketball is set. The Jayhawks beat Ohio State in a close one and Kentucky got past Louisville.

At the nine-minutes-to-go mark in games one through four of Kentucky's romp through the NCAA tournament, the Wildcats have had leads of 13, 11, 18 and 30 points. So it was significant that the Louisville Cardinals actually found themselves tied with Kentucky at that nine-minute juncture.

The NCAA Division 1 women's tournament gets criticized for not having enough true March Madness moments, when the Davids rise up and beat the Goliaths in nerve-jangling upsets. Such is the power structure in the women's game, with largely untouchable elite teams.

The payoff comes when all those elite teams gather, as they have in Denver, in such a show of force and talent that a fan tends not to miss the little guys.

Across America, libraries used to reach out to readers by sending bookmobiles into school parking lots, street corners and rural byways. Now, those rolling reading rooms are becoming scarce — too costly and outmoded, some say.

One town in northern New England just lost its bookmobile. The Cobleigh Public Library in Lyndonville, Vt., had managed to keep its van rolling until about a month ago, when it died.

The typical first-time mother takes 6 1/2 hours to give birth these days. Her counterpart 50 years ago labored for barely four hours.

That's the striking conclusion of a new federal study that compared nearly 140,000 births from two time periods.

One big implication: Today's obstetricians may be rushing to do cesarean sections too soon because they're using an out-of-date yardstick for how long a "normal" labor should take.

The U.S. Supreme Court heard arguments this week over key aspects of President Obama's health care law, including the expansion of Medicaid and whether the court even had the right to hear the case. But the core of the challenge mounted against the Affordable Care Act hinges upon its individual mandate, which requires almost every American to have or buy health insurance.

The sale or possession of liquor is strictly forbidden by the tribal government of the Pine Ridge Reservation in South Dakota. But there is a tiny town just over the border in Nebraska that does sell alcohol, in massive quantities, and mostly to tribal residents.

And now a longstanding battle over beer sales has spilled into federal court.

Despite their current opposition, the individual mandate originated with Republicans. Weekends on All Things Considered host Guy Raz talks to former Sen. Bob Bennett about the Republicans' support of the idea. During his 18 years in the Senate, Bennett, a Republican, co-sponsored health care reform bills containing the individual mandate.
