This time on Did You Know Gaming extra, we take a look at how a graphics artist who worked on Nickeldeon's SpongeBob SquarePants: Battle for Bikini Bottom hid a dirty secret in the game, how Monty Python's Eric Idle had a voice sample hidden away in Terry Pratchett's Discworld games for 20 years, and one Japanese developer's hunt for a seductress was hidden in the code of Ganso Saiyuuki: Super Monkey Daibouken. We finish it all off with a cameo appearance from Penny Arcade within Bandai Namco's Tekken 6.
