%N A self-describing sequence in English and in base 2 (see the Comments section for the explanation).

%C Replace 1 with "consonant" and 0 with "vowel"; the sequence now describes its own succession of consonants and vowels.

%e The sequence starts with:

%e 1, 0, 1, 1, 0, 1, 0, 1, 1, 1, 0, 1, 0, 1, ...

%e We get, after substitution:

%e consonant, vowel, consonant, consonant, vowel, consonant, vowel, consonant, consonant, consonant, vowel, consonant, vowel, consonant, ...

%e And this is indeed the description of what we just read:

%e consonant (C), vowel (O), consonant (N), consonant (S), vowel (O), consonant (N), vowel (A), consonant (N), consonant (T), consonant (V), vowel (O), consonant (W), vowel (E), consonant (L), ...
