Awesome/hilarious episode,
The highlights:
Another Brian/Stewie plot, sweet!!!!!
Peter sneaking to the cookie dough, hahahahaha.
Stewie going back in time to make a comeback with that snap was classic, hahahahaha.
Stewie ruining Brian's life and stealing Brian's best lines was great, cool that his evil roots always come.
Stewie doing the
Peanut Butter Jelly Time song, awesome


!!!!!
Brian/Stewie go back in time again, yaaaay!!!!!
The Cleveland Show Promo, hahahaha.
The Brian/Stewie musical notes, hahahaha.
The dancing talking snake, hahahahaha.
Bertram is back,
YAAAAY, nice that my favorite villain finally returns


!!!!!
Leonardo da Vinci is Stewie's ancestor, weird/interesting which Stewie is Italian, Seth, you're a genius!!!!!
Bertram's evil plan to kill Leonardo da Vinci was great which he'll be creating a time paradox, yikes!!!!!
The disturbing Thomas Edison gag.
Stewie vs. Bertram in the sweet flying machines.
The Italian guys being Fonzie, hehehe.
Woooooow, Bertram succeeded in killing Leonardo, farewell Leonardo.
Bertram's death surprised me, R.I.P. Bertram, you're awesome and you'll be missed, but I hope they bring him back, he had alot of potential.
Stewie replacing Leonardo da Vinci was beautiful.
Brian saving Stewie from his frozen slumber was nice.
Brian mentioning getting Meg to make Stewie wake up was brilliant, hahahahaha



.
The
Back To The Future references in the episode were awesome.
Wallace Shawn was terrific as Bertram.
Joe Faherty from
Back To The Future Part 2 was awesome as the delivery priest.
After bringing back Bertram, I hope they bring back the other forgotten old villains who're Gloria Ironbachs, Patrick(Lois's psychopath brother), Bob Grossbeard, and O.J. Simpson(his episode was hilarious!!!) since they were awesome villains way back.
