Well yes and no. If you stick display_bad_action in the TimeKeeper  
class it doesn't matter whether you call it from another method  
before it "sees" the definition. The rule is, before you call a  
method (at runtime chronologically, not necessarily before you type  
the code to call the method) it must be defined.

so

class A
    def a
        b
    end
    def b
       puts "B called"
    end
end

a = A.new
a.a

is fine.
