Am I crazy?

If I can't put global methods in application.rb, where do I put them,
and how do I call them? And shouldn't this work? Is there anyplace I can
see where Rails is looking for this method?

Maybe you just need to give ruby an object to send this method to?

C:\rails\test>ruby script/console
Loading development environment.

self.class

=> Object

msg

NameError: undefined local variable or method `msg' for #<Object:
0x284fa38>
        from (irb):2

a = ApplicationController.new

=> #<ApplicationController:0x48c3ad0>

a.msg

=> "msg"
