Penny Arcade Expo 2009 organizers have officially announced their keynote speaker. This year's speaker will be Ron Gilbert, who has become legendary for his work on classic LucasArts adventure titles like Maniac Mansion and the Monkey Island titles.

"This is an unbelievable moment for us. I wasted an entire family vacation one year trying to figure out how to win that stupid spitting competition," said Penny Arcade's Robert Khoo.

Over the course of a twenty-year career, Gilbert has created the SCUMM scripting language, served as creative director at Hothead Games, and been inducted in the Computer Game Hall of Fame.
