If you're a close follower of Jerry Trainor, then you're familiar with his wailing ways. But when did all the screaming start? During his interview on Conan, he took us back to his yelling beginnings. "I used to do a show before iCarly, Drake and Josh, and I was a crazy person that screamed all the time," he said. "I was quiet and then I would scream. And then I was Spencer and I would scream even more, and so now I've kind of just fallen into this screaming path."
