That was Molotov, the last of the OG Bolsheviks:

In 1986 Molotov was watching TV one day when Soviet Foreign Minister, Edvard Shevardnadze came on the news making some statement. Molotov rose from chair in a rage, shouting “What the hell is he saying! That’s revisionism! Pure revisionism! Worse than revisionism! Has he gone off his head? I hope Stalin hasn’t gotten wind of this yet, or there’ll be hell to pay. Tell Shevardnadze I want to see him in my office TODAY at 4:00 pm SHARP. And he better have a good explanation for this garbage!”

When they heard the shouting, his grandchildren rushed into the room and tried to calm him, saying “Grandpa relax! It’s just the news. You’re not Foreign Minister anymore. It’s 1986. Stalin’s been dead for 30 years.” Molotov calmed down and muttered “I’m sorry. I’m sorry. I just got so worked up. My memory isn’t all it used to be anymore.”
