If you don't stop being mean, my sister will come and beat you up!

David Pratt was looking so bad at the all candidates debate for Ottawa-West-Nepean on Wednesday night that he had to call in the big guns....his sister.

At the end of the debate, a woman from the audience seized the microphone and accused the Harper government of muzzling scientists, until an official wrestled the microphone from her hand. A shouting match ensued between the woman and members of the audience.

The woman later told a CBC reporter that she was Christine Pratt, the Liberal candidate's sister. On Wednesday, the Baird campaign contacted CBC News to ask how it could get a copy of that footage.

Priceless, this practically writes itself.

We're better off with Harper.
