That reminded me of the compiler that used to include a large poem in every binary, just for shits and giggles. You've heard of a magic number, it had a magic sonnet.

I thought it was early versions of the Rust compiler, but I can't seem to find any references to it. Maybe it was Go?

EDIT: Found it: 'rust-lang/rust#13871: "hello world" contains Lovecraft quotes' https://github.com/rust-lang/rust/issues/13871
