As expected, Twitter erupted with jokes and memes as former Prime Minister Manmohan Singh began his scathing criticism of the demonetisation drive by the government in Rajya Sabha. Most responded in glee that "Singh has finally sang". @SirJadeja tweeted, “Dr Manmohan Singh discovers his voice. Now all Congress needs is Rahul Gandhi to discover his brain." @bigotry_watch posted, “How times have changed, Manmohan Singh spoke and Narendra Modi was scared of speaking.””MMS talking about organised loot and legalised plunder. Everybody is allowed to be nostalgic once in a while," said @coolfunnytshirt.
