Also, things I didn't know that I now know: Adam Goldberg is a half-Jew who's an LA Jew (and not a New York Jew). This is relatively enjoyable rainy-day entertainment: you might not live in sunny LA, but at least your day-to-day doesn't put you through this:

Former Village Voice columnist Tricia Romano has a piece in Thursday's New York Times profiling the phenomenon created by Ryan Heffington, a "choreographer, performance artist and designer" who has created something called "Sweaty Sundays," a weekly aerobics, errr, dance class held in a performance space in the heart of LA's very own Williamsburg.

Here, members of this creative class - artists, photographers, fashion designers and screenwriters - dance off the previous night's excesses to a soundtrack of indie rock, techno, and 1980s new wave hits. And they do it while looking fabulous in Jane Fonda leg warmers and belted leotards.

"It's kind of an American Apparel ad come to life," said Terence McFarland, 40, the executive director of the Los Angeles Stage Alliance, who is a regular.

On a recent Sunday, Christopher Kreiling, a 33-year-old visual artist, was among the first to arrive. It was his first time, but he already had the look down: a pair of very short white corduroy shorts, a pink-and-white striped tank top and the all-important headband.

"I just had 10 cigarettes and a coffee," he said. "I'm like, ‘O.K., let's go.' "

Heffington says that the class has become so popular with the local idiots that he's added a second Sunday class as well as a weeknight one called "Wet Wednesdays." And don't fret over not being able to participate in the fun yourself if you don't happen to live in the LA area, because there's a DVD coming soon. Yippee!

Now, the real question the article about this hideous trend brings up is what will the Williamsburg hipsters do to top it? Sorry Williamsburg, but your little kickball and tetherball retro-fitness trends don't stand up against this. You all need to step it the hell up! Surely it's the lack of availability of things such as "Sweaty Sundays" that stokes Tricia Romano's smoldering hatred of New York. Win back her dark, jaded heart! Do it for New York!
