If you are not familiar with Rudy, but want to know how his mind works, take a look at the Charlie Zelenoff story. He is a self declared champion boxer that simply cannot acknowledge that he is not talented.
Charlie pays people to spar, then he goes crazy on them, usually taking them by complete surprise. He declares victory, and keeps the delusion going.
Rudy J is like that, but in the gaming world. His true value is not in gaming ability, but in providing comic relief.
