Jed Olsen is your average American. He's easy-going, friendly, punctual and respectful. It's what he wants you to think of him. He sounds like a friendly neighbour, but in reality he's a psychopath who finds it hard not to get back to his infamous hobby. He always tries to be calm and always says how emotionally underdeveloped Frank is. But once his ego is hurt or he had too much of Frank's bullshit, he loses his temper and can say things that make everybody regret they have ears. He finds it funny when he makes Frank mad (but hates when Frank makes him mad). He's sadistic and cold-blooded, doesn't know how to care about anyone but himself.

It's important to sound like a 30-35 year-old-man not only with a voice changer but with your real voice as well. Please, provide at least one line with your real voice. If you think that a different wording would suit this character best, you can change it a little bit!
