A New York City cab driver was recently suspended by the Taxi and Limousine Commission for wearing a Nazi armband while driving his cab, a practice he believes is his right. "I'm a National Socialist — what you guys call a Nazi," he told CBS New York. "I am. I'm a believer of it."

A Tokyo cab driver has been arrested for allegedly feeding his female passengers snacks laced with diuretics so he could satisfy his fetish for seeing them lose control and urinate on his back seat.

New York City's Taxi and Limousine Commission has approved a new style guide for the city's cab drivers. So, what is acceptable attire and what isn't?

The keffiyeh trend has reached its saturation point—we mean you, Lauren Bush!—and is now confusing cabdrivers. "You visit Saudi Arabia?" last night's cabbie asked me. "You wear something from my country!" The explanation was unspeakable: "Actually, sir. Some twentysomethings, who live in the city and are sort of maybe 'hip,' we enjoy appropriating things from other cultures for no reason other than because it's sort of ironic or maybe meta and edgy-ish and shit, actually, I have no idea why I'm wearing this and I hope this ride is over soon."

Novelist Roxana Robinson loves the world and all its peoples, who are not so different from one another as you might imagine! She also, being a novelist, loves novels. So imagine her joy when those two things coalesced in an international literary festival: "The idea of this gave me a carnival sort of feeling, a fine fizzing excitement. There would be writers from all over the world, reading from their work, onstage." Omg, like knitting a kitten sweater while sipping hot cocoa! But before her excitement could fully finely fizz, she had to get to the festival in question, and the method of conveyance she chose was a taxicab. It was a lucky day for that cab driver, because Roxana opened up a whole new world to him: the magical world of the English language.
