Late Tuesday, Tesla and SpaceX CEO Elon Musk accidentally published his phone number on Twitter in a note intended for John Carmack, Oculus’ chief technology officer, via private message.

“Do you have a sec to talk? My cell is …” read the tweet, followed by the phone number.

Shortly after it was published, it was quickly deleted, not without being in full view of his 17 million followers.

According to users who attempted to dial the number, a recorded message from the God of War video game could be heard, delivering the following phrase in a grumbling, echoed voice: “By the Gods, you’ve done it. Somehow you’ve found your way here to me. I offer you my congratulations and my respect.”

In classic Twitter fashion, many users took Elon Musk to task for his mishap.

In response to the story, John Carmack issued his own Twitter response in a shot to Business Insider, who reported the story while offering too few details of his relationship with Musk to his liking.

John Carmack leads Facebook’s virtual reality subsidiary, Oculus, after a long career in computer game design where he helped introduce mainstream hits such as Doom, Wolfenstein 3-D, and Quake, new concepts that emphasized three-dimension game design and first-person shooters with the ever-present “floating gun” at the bottom of the screen during gameplay.

Later on, he went on to start Armadillo Aerospace, a space tourism company, and the aforementioned Commercial Spaceflight Federation with Elon Musk, a group dedicated to human spaceflight industry best practices and safety.
