How do I undo True = False in python interactive mode?

So I tried the "evil" thing Ned Deily mentioned in his answer here. Now I have that the type True is now always False. How would I reverse this within the interactive window?

Thing to not do:

    True = False

Since True has now been completely overridden with False, there doesn't seem to be an obvious way to back-track. Is there a module that True comes from that I can do something like:

    True = <'module'>.True

You can simply del your custom name to set it back to the default:

    >>> True = False
    >>> True
    >>> del True
    >>> True
