The online commotion over Lenin began Saturday, when local Russian media posted a mysterious photo of doctors rushing into the mausoleum.
Others launched into tongue-and-cheek conspiracy theories, suggesting the photo with the paramedics was proof that Lenin's alive. "It's no accident that the mausoleum closes for lunch," one user wrote.
Some users broke out into poetry and song, including Vladimir Mayakovsky's famous verse "Lenin lived, Lenin lives, Lenin is to live forever."
Others still took a shot at Russia's medical system, joking that this was a case of "Russian medicine in action," with paramedics "responding to a call made 100 years ago."
A few English-language Twitter users also heard about the news, coming up with similarly hilarious comments and a few memes.
