Open the browser to http://codegolf.stackexchange.com Your job is to open a browser window of the default browser to http://codegolf.stackexchange.com.

Your code must open the browser itself, and cannot rely on an open one. 

This is code-golf, so the shortest answer in bytes wins.

Not winning, but sure was fun.  As of right now, I'm only 1 bytee behind python!
I need webbrowser
Now open &quot;http:ppcg.ga&quot;

Explanation:
I need compiles to import $1 with webbrowser being the module.
Now runs the following command from the module as module.command with the arguments of anything following.
So this compiles to:
 
#!/usr/bin/env python3
import webbrowser
webbrowser.open(&quot;http:ppcg.ga&quot;)

I do end up needing the http: part though, and it can't be shortened.
