Thanks to this Task:
{T15401}
And thanks to the user speck, I discovered there are some cowsay-related binaries:

Probably most of these are unused, since now Cowsay it's written in PHP and part of Arcanist:
https://we.phorge.it/source/arcanist/browse/master/src/utils/PhutilCowsay.php
Why I think it's important to remove unused binary files:
- the ITSec team is less scared if they cannot find less legacy binaries around
- the embed team is more happy to save extra bytes from the working directory or phorge in production
- it seems that these things need to be updated with time to receive updates (e.g. security updates), but actually only the "cows" files need to be updated (just to have more)
