The biggest difference between actually playing the game and playing on your couch is that at home you can answer EVERY question you know the answer to - on the game itself you are hostage to the buzzer. If you are a millisecond too slow, you don't get to answer.
My favorite Jeopardy! story is the one they tell about the contestant who decided to relax by having a few drinks. She couldn't buzz in during the first part of the game - during the break (they film in real time) the game show people went to check out her buzzer - turns out she was using the big, heavy pen you use to sign in and for final Jeopardy! as a buzzer!
And I'm sorry to burst your bubble on Alex - but it's been covered by other contestants. He really is quite self-absorbed and impressed with himself (despite having the answers right in front of him!)
