The Venture Bros.

Dr. Venture finally learns the secret of his recurring womb nightmares when a stomach tumor turns out to be something far more sinister. In a fit of jealousy over their mistaken belief their father is pregnant, the boys run away from home. But their newfound freedom is short lived once they run afoul of the law and land themselves in a 'Scared Straight'-style outreach program headed by none other than the recently incarcerated Monarch.
