I agree. R-Truth's heel persona last year was something that was simply genius since his "What's Up!" crap was becoming quite a snoozefest. His promos were unique and hilarious. In my opinion, his first promo after turning heel last year was his best promo in the WWE and one of the funniest heel promos in a long, long time. The way he would react to the crowd and the "What?" chants made him much more effective as a heel. There was even a time where I was pulling for him to win the WWE title since he was so entertaining with his conspiracy stuff and a WWE title run from him, would have definitely been interesting to see.
I do think the Little Jimmy stuff is funny at times but I agree that it can get a little boring.
