It's " I'll be Bach!" And I jokingly say it with an exaggerated German accent all the time. In truth, he's one of my fave characters in real life. My son and I always jke about it too while we're laughing at the innane humour of Family Guy.
We have such little minds. But we need simple Guy Humour to get us through the day. While my daughter tries to solve all the world's problems when she's not in the bathroom, Ev and I just laugh.
And solve all the weighty world problems, like go and watch THE Edmonton Trappers of some obscure baseball league I used to cover or the Winnipeg Goldeyes, which I also used to cover.
This above is my son, Evan, apparently contemplating the future of the planet -- or the equally important responsibility of solving all the world's problems.
With the assistance of the computer above and a baseball bat he can always use when he MUST resort to brute force, he will endure.
