He's a holy grail
I think that if Jesus was a popular High School guy, he probably would be like that. This was the best in the series because it simply had gag after gag. It is also unpredictable, as in I was seriously not expecting Evil Josh to succeed in beating Jesus. I also love all of the little lines like, "He thinks he's better than the Beatles". Another funny gag was having the drums disappear and then he asks where they came from. Oh, and in case nobody else was able to notice it, Evil Josh's hair then turns purple.
