Put a little danger in your pushes and take a ride on the pushroulette. The pushroulette will play a random 5 second clip from Soundcloud on any mac (it requires afplay for the time being) after every git push.
brew install ffmpeg --with-libvorbis --with-ffplay --with-theora
Then you can just install pushroulette via pip:
sudo pip install pushroulette
If you don't have pip installed yet you can install pip like so:
sudo easy_install pip
Finally modify your git push alias to call pushroulette (all aliases can be found in ~/.gitconfig)
[alias] ... ph = !git push && python -m pushroulette ...
