You probably won't be one of the few souls to meet Pope Francis on his visit to the U.S. next week. But hey, it could happen, and if it does, don't you want to be ready?

Here's a primer on what you need to know so, at the very least, you'll be well-prepared for small talk about him, if not to him.

Etiquette

The pope is never introduced. He literally is a man who needs no introduction. (You, of course, ought to be introduced by somebody.)

Flavia Pennetta has defeated Roberta Vinci to win the U.S. Open, in a women's final that was an all-Italian affair.

The two women have more in common than their nationality. They were opponents and doubles partners as kids, the Associated Press reports. It was the first major final for both. And they were both outperforming expectations just by being there: Vinci was unseeded, and Pennetta was the 26th seed.

Mei Xiang, the female giant panda at the Washington National Zoo, gave birth to two live cubs on Saturday.

The first cub was born in the afternoon, and the second cub emerged 4 1/2 hours later. Both appear to be healthy, the zoo reports.

Typos are embarrassing in emails, dangerous in cover letters, cringe-inducing when they're on social media.

But it could always be worse: That mistake could be inked into your skin.

This September, a few unlucky Colombians will be freed from that plight. An institute dedicated to studying and teaching the Spanish language is offering to fix tattooed typos forever — free.

Federal regulators are fining Fiat Chrysler $105 million for failing to acknowledge and address safety defects in a timely fashion.

The civil penalty — the largest ever imposed by the National Highway Traffic Safety Administration — will be accompanied by three years of "unprecedented" federal oversight, the agency says. Fiat Chrysler has also agreed to buy back some vehicles from their owners.

The U.S. team won the Women's World Cup soccer final 5-2 in a game that brought U.S. fans to their feet, reduced polished sportswriters to all-caps expressions of awe and rewrote FIFA records — and that was just in the first half.

The game began in spectacular fashion: In the first five minutes, captain Carli Lloyd scored two swift goals — the fastest two goals in FIFA history, according to the FIFA Women's World Cup Twitter account.

Just a few minutes later, Lauren Holiday brought the score up to 3-0.

Nearly 500 people were injured at a water park in Taiwan after an explosion at a music event caused a fire to break out Saturday night.

The fire started during an evening rap performance in New Taipei City, NPR's Frank Langfitt, reporting from Shanghai, tells our Newscast unit. The accident at Formosa Fun Coast was caught on cellphone video.

"At one point, green powder shot out from the stage over the audience," Frank says. "The powder quickly ignited, enveloping fans. Some people staggered around on fire, while others collapsed to the ground."

It took nearly four decades, but a horse has once again attained the honor that some call the most difficult achievement in sports: American Pharoah, after winning the Kentucky Derby and the Preakness Stakes, ran to victory in the Belmont Stakes as well.

He's the first Triple Crown winner since 1978. With his win, a total of 12 horses have now achieved the feat.

American Pharoah took the lead early in the mile-and-a-half long race, with Frosted close on his tail. From there, the colt never gave up the front position.

Amtrak will be restoring rail service between Philadelphia and New York at 5:30 Monday morning, the rail service announced Sunday.

Service between the two cities had been shut down since Tuesday, when train 188 derailed in Philadelphia, killing eight and wounding more than 200.

The affected section of track is part of the Northeast Corridor — the busiest railroad in America.

American Pharoah is the king of the nation's horse races this month: in a driving rain, the Kentucky Derby winner took home top prize at the Preakness Stakes Saturday.

Ridden by Victor Espinoza, he left the other horses at Pimlico Race Course eating his mud; with an unofficial time of 1:58.46, he led by an impressive seven lengths.

If he can win the Belmont Stakes on June 6, he'll be the first Triple Crown winner since 1978.

American Pharoah, ridden by Victor Espinoza, has won the 141st Kentucky Derby with a time of 2:03:02.

He raced to victory before the largest Derby crowd ever — 170,513, reports The Associated Press.

American Pharoah, owned by Ahmed Zayat, was the favorite heading into the race at Churchill Downs in Louisville. He had to fight Firing Line and Dortmund for the victory; the three were neck-and-neck (and neck) for a stretch, but American Pharoah pulled ahead at the end. Firing Line came in second.

March Madness has begun: The NCAA has announced the seeds for the 2015 men's basketball tournament.

As expected, Kentucky is seeded first in the Midwest Region, and is also the top seed overall. If the thus-far undefeated team wins the tournament, they'll be the first undefeated men's basketball team in nearly four decades.

In the East, Villanova won the top spot; in the South, that went to Duke, and in the West, Wisconsin was seeded No. 1.

Ships and planes have resumed the search for AirAsia flight QZ8501, which lost contact with air traffic control on Sunday. The search efforts, which were suspended overnight, picked up again at dawn, The Associated Press reports.

Bambang Soelistyo, the head of Indonesia's search and rescue agency, says the plane has likely crashed into the ocean, Reuters reports. Soelistyo calls that an "initial estimation."

When it comes to the perfect holiday sweater, for many people, cheesy is good — tacky is better — and astonishingly ugly is best of all.

The demand for ugly holiday sweaters has reached such a height that it's changed how businesses stock for the season, as Eleanor Klibanoff reported for us on Weekend Edition Saturday. Wal-Mart and Kohl's sell new "vintage" ugly sweaters, and actual vintage stores have had to start searching for new stock to sell.
