On this week's show you'll hear an excerpt of Lexicon Valley. I hope it speaks to your inner word nerd. There is nobody on earth, I assure you, more word-nerdier than Mike Vuolo, who is the brains behind this operation.

On May 27^th a Pentecostal pastor who handles poisonous snakes as part of his religious tradition was bitten, and in the absence of any medical attention, he died.  One of those who witnessed his death and decided not to call for help was Lauren Pond, a photojournalist who had been documenting Wolford for over a year.  Bob talks to Pond about where journalistic responsibility and respect collides.

Four Tet - 128 Harps

Bob talks to incoming police chief Janee Harteau about the department's decision to post video of their own officers at large public events.

The NBA finals, between the Miami Heat and the Oklahoma City Thunder, are going on this week and next. The Heat and the Thunder are singular because they have reached the championship series -- but are also singular because they are not plural. And for copy editors that presents a very serious challenge. Bob speaks with Deadspin Managing Editor Tom Scocca about the grammatical dilemma.

Mad Men's fifth season is over. From it's start, part of the show's allure has been the way it meticulously creates Manhattan in the 1960’s. Period specific language is part of that, but verbal anachronisms sneak in with surprising frequency. In this excerpt of the Lexicon Valley podcast, Bob Garfield and former OTM producer Mike Vuolo discuss the linguistic anachronisms in Mad Men.

When the conflict in Syria began it was relatively simple - a tyrant versus his people. After more than a year, it's become much more complicated.

The Replacements - Kids Don't Follow

The New York Times reported this week that the Assad family employs Western PR firms to polish its image for the rest of the world. A few years ago, Harper’s contributing editor Ken Silverstein went undercover and approached PR firms as a fake representative of a tyrant who needed to improve his image. He talks to Bob about what he learned.

When protesters try to make themselves heard at this summer’s presidential conventions they’ll likely be penned by police some distance from the candidates. Law professor Ronald Krotoszynski argues in a new book that that’s a violation of the 1^st Amendment, specifically the right to petition the government for a redress of grievances. He explains to Bob why protest is a form of protected speech and why proximity to the government officials you’re protesting is paramount.

The White House announced this week that they’d killed Al Qaeda’s number 2 operative, but, following standard operating procedure, would not tell reporters how they'd killed him. Why? Because they killed him by targeted drone strike, a program which is widely known about but still technically classified. The New York Times reporter Scott Shane tells Bob that the administration's coy attitude towards classified secrets is stifling public debate.

This week the Wall Street Journal reported Facebook's plans to open up the social network to children under 13. As of now, preteens are not permitted to use the site, mainly because Facebook would have difficulty complying with COPPA, the Children's Online Privacy Protection Act -- the federal law regulating how companies can collect and use information about kids. Danah Boyd talks to Bob about COPPA's origins.

Fourtet - 128 Harps

Aspirin, zipper, thermos, yo-yo -- even heroin was once a registered trademark. Today, they're generic product categories. Could the same happen to Google? It's already a recognized verb.

New Country Rehab - Ramblin' Man

China is increasing its number of movie theatres and the number of American films that can be shown in them.  And China is already the second largest market for American films in the world.  So Hollywood is anxious to take full advantage of China’s potential and is busy making, and changing, its fare to appease the notoriously sensitive Chinese government.  Bob talks to USC professor Stanley Rosen about what Hollywood's appeasement of China looks like at the movies.

This year has seen a wave of independent video game developers competing for attention and money on crowdfunding websites like Kickstarter. John Walker, one of the editors of the gaming criticism website Rock Paper Shotgun, talks to Bob about how he and his colleagues have opted to decide the fate of this field of hopefuls. 

Live sports broadcasts account for a big part of your cable bill. Why? Because cable providers know they can count on sports to draw large audiences even as audiences shrink for other types of programming. Peter Kafka of the website All Things Digital returns to talk with Bob about the remarkable rise of ESPN and the importance of live sports to the cable ecosystem. 

Web TV services, DVRs, and on-demand TV encourage us to ignore the broadcast schedule and watch at our convenience. So what will become of the experience of watching the same show at the same time as your friends? Bob sits down with David Carr, media critic at the New York Times and Matt Zoller Seitz, New York magazine's TV critic, to see if the water cooler will evolve or perish.
