Pie-flinging Jonathan May-Bowles pled guilty to assault and harassment charges at a London court Friday.

The comedian and activist was charged with the crimes after he attacked Rupert Murdoch with a shaving cream pie during a parliamentary hearing on July 19. Murdoch was being questioned by British MPs over the News of the World phone hacking scandal when May-Bowles -- who goes by the nickname Jonnie Marbles -- stood up from the public gallery and pied the media mogul.

Murdoch's wife Wendi Deng Murdoch famously came to her husband's rescue, blocking some of the pie and slapping May-Bowles a number of times. May-Bowles was apprehended by police immediately.

In court, May-Bowles remained quiet, saying only his name, address and his plea. His father, as well as a number of friends, supported Marbles in court. David Marshall Bowles is 81 years old, just one year older than Murdoch.

Murdoch did not support the assault charge, according to The Telegraph.

The hearing lasted only 15 minutes. Sentencing will take place on Aug. 2.

"I'd just like to say, this has been the most humble day of my life," May-Bowles said to the press on the court house steps. Marbles was mimicking Murdoch, who opened his Home Affairs Committee hearing with the same words.

A self-described anarchist, Marbles is an "activist, comedian, father figure and all-round nonsense," according to his Twitter profile. He called Murdoch a "greedy billionaire" before jumping from the gallery at the House Affairs Committee.

“It is a far better thing that I do now than I have ever don before #splat," May-Bowles tweeted before the pastry-attack.
