Episode 'Family Guy' Season 9, Episode 17 - 'The Big Bang Theory' Recap

When Stewie gets burned by Brian, he gets an idea: go back in time, and he can always have the perfect comeback! Come on, admit it...you've thought about it too. After a few experiments (and stealing Brian's "Peanut Butter Jelly Time" gag), Brian finally catches on.

But when the two struggle at the controls, they get sent outside of the space-time continuum. Hey, it's purgatory! Or at least, that's how they drew it back in the day.

It isn't until Stewie gets an idea to blow up the return pad to propel them back into reality that they find their way back through a rather expensive-looking wormhole. When he finds that the cosmic background radiation matches the energy spectrum of the return pad, he determines that he, Stewie Griffin, created the universe. What is this, Futurama?

What? Bertram's back! He hears about the time machine, and plans to remove Stewie from history by killing one of his ancestors. By doing so, he tears holes in the fabric of space-time, just like how Doc Brown warned us. When Stewie and Brian travel back to stop him, they discover that Stewie is descended from Leonardo Da Vinci. Da Vinci in a cartoon? Again, what is this, Futurama?

So, then that would mean that Peter and Chris are also descended from Da Vinci. I guess those genes just pop up when they feel like it. Although, I guess Chris is a pretty good artist...

Cue the extended aerial battle between Stewie and Bertram. Why do Da Vinci's flying machines have missiles on them? It all ends with Stewie giving Bertram a Schwarzenegger-esque pun. But with Da Vinci dead, Stewie must become his own ancestor. For the final time, what is this, Futurama?

Ahhh, there's the "Back to the Future" reference I was waiting for. Brian gets five hundred year old letter from Stewie, who froze himself cryogenically. Brian gets a candle.

Cutaways: Neil Armstrong and the ground control guy; Planned Parenthood clinic on Halloween; Thomas Edison "experimenting."
