Have you got a link to that, or a quote? I’ve had a search but can’t find anything.

Here it is:

---

Во тьме ночной

Пропал пирог мясной.

Пропал бесследно, безвозвратно.

Куда и как девался, непонятно.

---

In the darkness of the night

A meat pie vanished.

It disappeared tracelessly, irrevocably.

It's a mistery (literally it's ununderstandable, one can have no idea) where has it gone.

---

In Russian it rhymes.

Once their mother baked a meat pie meant to be served to the guests and everybody for a supper and his younger brother ate the entire pie secretly he didn't tell anybody and wrote this poem.

As far as I know this was the one and only poem Lenin wrote.

I do wonder if it was really his brother who ate it. Lenin was reportedly the "worst" behaved of his siblings, and though he usually owned up to his behavior as a kid there was one incident his sister recounted in which he broke a vase and tried to deny any knowledge of the fact, but then weeks later, one random night broke down crying to his mother and admitted that he had lied about the incident. Just an anecdote from a childhood but amusing when you consider the sheer magnitude of destruction he later deliberately created as an adult.

second the other response. I've read a fair bit about and by Lenin and never heard of this poem. Care to share a link by chance?

See above.
