Abbott and Costello's famous "Who's on First?" routine still stands as one of the greatest comedy sketches of all time. It was a feat of rapid-fire dialogue, flawless comedic timing and devastating wit.

But could you do it without saying a word?

The answer appears to be yes. After Jerry Seinfeld broke down the classic skit on the MLB Network recently, NPR's Mike Pesca wound up with a peculiar email in his inbox.

It was a link to an American Sign Language (ASL) version of the skit, sent by a friend. It was amazing, Pesca says.

Among the many contenders who could wind up becoming presumptive Republican nominee Mitt Romney's running mate, there are some potential surprises — like former presidential candidate-turned TV and radio host Mike Huckabee.

Putting Huckabee on the GOP ticket could certainly liven up the presidential race. In addition to being a respected former governor of Arkansas, he's well known for his good-natured public persona. At a Huckabee campaign event, you might find him playing an electric bass with the old-time rock 'n' roll band Capitol Offense.

In 1964, John Coltrane moved from Queens, N.Y., to a brick ranch house on a 31/2 acre wooded lot in the quiet suburb of Dix Hills. This bucolic setting — 40 miles east of the city — is perhaps the last place you'd expect to find a musician creating the virtuosic jazz that Coltrane is famous for.

Ernest Hemingway began his second novel, A Farewell to Arms, in 1928. He says, in an introduction to a later edition, that while he was writing the first draft his second son was born, and while he was rewriting the book, his father committed suicide. He goes on to say, with his famous economy, "I was not quite thirty years old when I finished the book and the day it was published was the day the stock market crashed."

Rachel Joyce's novel The Unlikely Pilgrimage of Harold Fry is about a man who very suddenly, with no warning or planning, sets off on a pilgrimage from the very southernmost part of England to the very northernmost part. It's a old-fashioned pilgrimage: He walks all the way, talking to the people he meets, on his way to the bedside of his old friend Queenie, who is dying.

Spain is a country that partied for days after winning the European Soccer Championships earlier this month.

Soccer dominates the sports scene, and the Spanish side is favored to win Olympic gold in London this summer. But Spain is also a basketball powerhouse and is currently ranked No. 2 in the world behind the U.S.

At a school gym, you'll find Spaniards who actually know that. Basketball is growing in popularity among kids, especially girls.

"Basketball is a sport that's beautiful for me," says 13-year-old Lucia Gutierrez.

With the largest HIV epidemic in the world, no nation has been more affected by HIV and AIDS than South Africa, but the country has also had one of the most conflicted responses to the epidemic.

A decade ago, as the virus was spreading rapidly, then-President Thabo Mbeki was questioning the link between HIV and AIDS. His health minister was advocating the use of beetroot, garlic and lemon juice to treat it.

Now, years later, South Africa is trying to make up for lost time. The nation is attempting to put in place a cutting-edge HIV treatment and prevention program.
