You can't do it in Ruby unless you use Mauricio's "evil" library. (He
named it, I didn't) which has a #become method, a la Smalltalk.

If it really is just one method you're concerned with, you could always
redefine it. Ruby won't let you change the class of an object, but it
will let you arbitrarily add/change/delete stuff in the object.
