I noticed that too.  Super works fine in cases of inheritance, but the
example wasn't inheriting, it was reopening.

Though my first instinct was to try to use the "this" object in the
"else..." statement to just use the current object to call the original
method.  But then I remembered ruby doesn't have "this".
