So, McDonald's grimace tweets are as cryptic as ever. McDonald's just dropped a phone number, grimace, just dropped a phone number and has an announcement on the 6th. I'm considering it being one of two things. One, the McRib is back, or two, Grimus will unmask and unveil himself to be Jason Alexander, thus resulting in the grand reemergence of the McDLT. at McDLT, it keeps the hot side hot and the cold side cold.
