C is for...cock? The Sesame Street YouTube channel was taken down yesterday (and remains down) after horny hackers went wild and replaced videos of everyones favorite furry friends with hardcore porno clips. And not even the plushie kind!

We didn't get a chance to catch any of the NSFW action yesterday—it reportedly was taken down quite quickly—but San Francisco's ABC affiliate, KGO-TV, did and "reported that one of the adult videos was eight minutes long, but that none of them included Sesame Street characters."

For their part, Sesame Workshop, which produces the show put out an apology last night:

We apologize for any inconvenience our audience may have experienced today on our Sesame Street YouTube channel. Our channel was compromised and we are presently working with YouTube/Google to restore our original content. We always strive to provide age-appropriate content for our viewers and hope to resolve this problem quickly.

Meanwhile, while they work out restoring Grover and co. to YouTube, you can still find them on SesameStreet.org.

As for who did it? That is still up in the air, but a user named MrEdxwx who some blamed for the hack swears he didn't do it.
