Above: A real, genuine tweet that was sent from the official McDonald’s account this morning. It’s since been deleted and the account is back to doing whatever it is that an official fast food Twitter account does:

Breakfast for dinner is the best! We love that you're lovin' it, Dean. — McDonald's Corporation (@McDonaldsCorp) March 16, 2017

No word yet as to whether we’re dealing with a rogue employee, a hack, or what. (A fun twist: the McDonald’s “global chief communications officer” is former Obama press secretary Robert Gibbs.) More to come on this important story, no doubt.

Update, 10 a.m.: Apparently whoever did this was also briefly able to “pin” the tweet, which, for the non-Twitter-initiated, means selecting a tweet so that it always shows up first on your user page. It’s what people do with, like, the tweet they’re most proud of sending.

Update, 10:30 a.m.: McDonald’s is saying its account was “compromised.”
