default options example doesn't work for me

that example doesn't work for me, but if i do this, it does: http://pastebin.com/gxQLUxGW

assuming I fix the double quote issue that I just opened a ticket for, when I do it as stated on the readme, I get this when I just go to site.com/hello:

→ Notices and warnings

[1. WARNING]

Missing argument 2 for hello() in index.php line 50

Hello bob

But when i put a value... like site.com/hello/jim:

Hello bob jim
