Reverting to default template

When I override a standard method and put it in my controller, Rails
also wants a corresponding template to go with it. The default
template would be fine and I would rather use it than hand craft my
own. How to I tell Rails to use the default template even though I
have overridden a method in my controller?

For example If I add a "list" method to my controller, Rails also
expects for me to create a list.rhtml but I really don't need to
modify the default template because it would be fine.

Is there a way to do this?
