Deconstructing RumsfeldOffice: real or parody Twitter account?

Parody accounts are okay on Twitter.

But how can you tell if an account is for real? Twitter provides two tips:

The bio should indicate that the user is not affiliated with the account subject by stating a word such as “parody,” “fake,” “fan,” or “commentary,” and be done so in a way that would be understood by the intended audience.

and

The [account] name should not be the exact name of the account subject without some other distinguishing word, such as “not,” “fake,” or “fan,” and be done so in a way that would be understood by the intended audience.

And why do I know this? Because of a tweet – and the storm that followed it – that caused me to go “huh?” I’m still having trouble accepting that this is a legitimate, not parody, Twitter account. What do you think?
