"I'm sorry, Mark. I'm afraid I can't do that," Jarvis answers. "There are no good Nickelback songs."
"Good. That was actually a test," Zuckerberg responds. "How about just play some songs that our whole family likes."
The tongue-in-cheek comment did not sit well with Lavigne, prompting a visceral takedown addressed to "Mark."
"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," Lavigne tweeted Thursday. "When you have a voice like yours, you may want to consider being more responsible with promoting bullying, especially given what's going on in the world today. #SayNoToBullying #TheJokeIsOld #NickelbackHasSoldOver50MillionAlbums."
While Lavigne and Kroeger have been separated for more than a year, the two have remained friends. A month after announcing their separation in September 2015, the two were snapped working on new music together in a recording studio.
