Gmail, a pioneer in the grand tradition of elaborate April Fools’ jokes, scrambled to undo its latest one after disgruntled users complained that they had accidentally sent photos of mic-dropping Minions, the little yellow creatures from the movie “Despicable Me,” to their business contacts.

The feature was called the Mic Drop, and it was billed as a way to have the last word in long email chains by sending a GIF of a regal-looking Minion character literally dropping a microphone.

“Simply reply to any email using the new ‘Send + Mic Drop’ button. Everyone will get your message, but that’s the last you’ll ever hear about it. Yes, even if folks try to respond, you won’t see it,” said a Gmail blog post about the feature.
