If you're anything like me, you can never remember the argument order for alias_method. I always think to myself "it's the other way around than I think it is", but then end up doing it wrong anyway.

So here is my mnemonic for remembering it:

alias_method :alias, :method

The method name itself is the argument order. First the name of the alias, then the name of the actual method.

Need some more information about alias vs. alias_method? There is a great post on that on bigbinary.com.
