Facebook CEO Mark Zuckerberg got a stern talking to yesterday from 2000s pop icon Avril Lavigne, who took time out of her day to tell the tech titan to quit it with the cyberbully. Interestingly, Lavigne wasn't rushing to the defense of some awkward teenager destined for an internet shaming, but rather the Canadian band Nickelback. It seems that in a video promoting his home-built artificial intelligence the Zuck awkwardly attempted some humor in the form of a Nickelback jab.

"Dear Mark," wrote Lavigne, "Many people use your products - some people love them and some people don’t. Either way, you’re allowed your musical opinion however, your jab at Nickelback is in poor taste."

Poor taste or no, the joke was decidedly lame. In the video, Zuckerberg asks his self-programed butler to “play us some good Nickelback songs.” The machine responds, "I’m sorry, I’m afraid I can’t do that. There are no good Nickelback songs.”

Sick burn.

"When you have a voice like yours," Lavigne continued, "you may want to consider being more responsible with promoting bullying, especially given what’s going on in the world today. #SayNoToBulying #TheJokeIsOld #NickelbackHasSoldOver50MillionAlbums"

Hey Mark, stop it. Just stop it, OK?
