This is a cool tip that will work on and OSX Computer.
You can get your mac to sing and swear and talk anything via a simple Shell Script.
You can even get my mac to talk… I will be able to hear what you type ( But you can’t 
)
If you are on a mac, try this at home….
osascript -e 'say "Sheldon is Awesome!" using "Cellos"'
I can swear too, no computer needed, but it surely helps!
