Not everyone has seen "iRobot" (I haven't!). I used Luke Skywalker because he's probably the world's most famous science-fiction example of a biological human who has a robotic arm or leg. (Darth Vader and RoboCop don't count because they are "more machine than man." And Americans are familiar with Steve Austin and Jaime Sommers, the "bionic" television superheroes from the 1970s, but I figured most Russians haven't heard of them.)
LOL, awesome -... and until you said Luke Skywalker, I was picturing "Bionic Commando"... This is what growing up on video games has done to my brain..
