Late Thursday evening, HBO Max sent out a perplexing email that had subscribers — and even WarnerMedia CEO Jason Kilar — questioning what the heck is going on at the streaming service.

The message was brief, but very cryptic. According to screenshots, it had the subject line “Integration Test Email #1” and the body of the email simply read, “This template is used by integration tests only.”

Naturally, it left a bunch of HBO Max subscribers — and Twitter users wanting to get in on the avalanche of ensuing jokes — wondering what it meant or if it was some kind of marketing stunt (it wasn’t).

HBO Max apologized for the “inconvenience” in a tweet shortly after the email went out and even blamed an intern (who we surely hope still has a job) for the bungled email. In the immortal words of a certain fictional pop star, everybody makes mistakes and everybody has those days.
