"Met new Green MP Mojo at the induction thingy. Cracked a few jokes and sage comments, but nothing! Is she deaf or something? Rude b***h."
Mr Williams is far from the first MP to fall victim to Twitter parody.
John Key leads the pack, with at least five others using his name and image to tweet. Along with the Prime Minister's official account, Twitter hosts @JohnKeyPM, @PMJohnKey, @Not-JohnKey, @John-Keys-ID, and @RealJohnKey.
@RealJohnKey describes himself as "From Christchurch state house to King of the World. Now Prime Minister of Nu Zilland".
On Sunday, following National's election win, JohnKey-PM tweeted "Guess who's back with a brand new wrap?".
Mana Leader Hone Harawira also has a number of impostors, as does outgoing Labour leader Phil Goff.
The day after Mr Harawira's election win in Te Tai Tokerau, @Hone-MP tweeted "Didn't anybody notice I had my fingers crossed? #ElectionPromises", followed up by "There's nothing to do for the next three years. #BiElection Anyone" on Monday.
Green Party members Metiria Turei, Catherine Delahunty and Kevin Hague, National's Nick Smith and Aaron Gilmore, and Labour's Clare Curran are among the other MPs who are victims of mock accounts.
