Subject: How to Iterate Through a Class

How do I iterate through a Class so that I can perform some action on each object?  For example...

MyClass.each do {|obj| DO SOME STUFF}


It looks like I have to create the .each method in my class.  I tried something like what's mentioned here...

...but haven't gotten it to work.
