Last week, McDonald's posted a cryptic tweet, "U should text me about the next sauce drop." Beneath the caption was a graphic with the phone number 707-932-4826.
People who texted the number received a photo of a box of sauce packets covered with gold film. When lined up in the correct order, they spelled out the word "Szechuan." (Observant internet sleuths also pointed out that the phone number spelled out 70S-ZEC-HUAN.")
