Franny, director of the film Age of Stupid and founder of the 10:10 campaign to cut carbon emissions, was unhurt after the incident in Camden, North London, on Monday night.
She said she did not agree with the mayor 's politics and had voted for rival Ken Livingstone.
But she added: "If you ever find yourself down a dark alleyway in trouble I think Boris will be more use than Ken."
Before he was elected Boris, 45, urged people "to take a risk" tackling thugs and claimed the chances of being stabbed were "microscopic".
Police quickly contradicted his advice, urging people not to become heroes.
I know you like the Mirror crapper, sorry to disappoint you again
