Two Russian ambulance staff were snapped running towards the site of his resting place in Moscow’s Red Square.
The image sparked a wave of jokes online, with many referencing an episode of The Simpsons episode in which Lenin comes back to life to “crush capitalism”.
One user wrote: “Get ready bourgeois, Lenin woke up!”
Another added: “Lenin lives, Lenin lives, Lenin lives!”
“Lenin lives, Lenin lives, Lenin lives!”
The communist revolutionary’s body has been on public display at the Mausoleum, on Red Square, since 1945.
No official comment has been offered on the incident by Mausoleum staff or the Moscow ambulance service.
Some local media have reported the incident actually involved a tourist who had fallen ill.
Daily Star Online previously revealed there have been calls for a long-buried statue of Joseph Stalin to be placed next to one of Lenin.
A statue of the tyrant was dumped in a dam in the Ural mountains 62 years ago – after the war leader was denounced by his Kremlin successor Nikita Khrushchev.
Locals at first thought the silt-covered concrete-and-metal effigy might have been a discarded memorial to an unknown soldier.
But a nearby museum confirmed the dictator’s towering statue – once in pride of place in a local park – had been disposed of in Kusa Pond after Khrushchev’s famous secret speech denouncing Stalin and his personality cult three years after his death.
Now, activists are calling for a referendum in a bid to restore the statue and place it back in a prominent position next to one of Lenin – the hero of the 1917 revolution.
