Subject: Make a symbol represent a method?

I just read a FAQ page online about Ruby symbols and someone mentions this

Also, the entirely realistic reasoning for using symbols: If you 
are going to refer to a method name, use a symbol. Because by 
defining the method, the symbol exists anyway.

Can someone show me an example of this?  Is this referring to the method 
of a class?
