A fun easter egg in the "say" command is that "OS X" is said as "Oh Ess Ten".

You can also change voices with -v. My favorite is "cellos" since it sings to you.

It actually understands roman numerals, to a certain extent. E.g. `say LVIII` will say "58". However, `say MCMLXXIX` speaks some gibberish that ends in the word "six", for some reason.

It also knows how to say numbers up into the trillions but not more than that (although I feel like it used to).
