UPDATE at 4:05 p.m. Friday, Jan. 9: Read our latest about why officials think this was the product of a hack, here.

A downtown Los Angeles digital traffic sign was apparently hacked recently to state, “READ A FUCKING BOOK.”

L.A. Weekly contributor Daina Beth Solomon snapped a photo (above) of the variable message LED sign last night. The portable sign was near Bunker Hill.

The big question, of course, is who dunnit?

It wasn't immediately clear.

But the sign reflects a Twitter hashtag, #ReadAFuckingBook, that's been circulating since 2010. It's often used to punctuate a perceived act of ignorance.

“Not knowing #PaulMcCartney is almost as bad as the idiots that didn't know #MayaAngelou #Readafuckingbook,” is an example of one such Twitter message.

Other L.A. Twitter users, including a man who posed for a selfie of a one-finger salute, snapped photos of the trailer, perhaps in anticipation that the sign would be un-hacked today.

For some reason, we feel like curling up with a good book.
