Plot[]
Paradox was on another planet, when he heard a voice from Heaven.
(Voice): Paradox, I have a test for Phineas and Ferb.
(Paradox): Well, Jesus, what is it?
(Jesus): Here it is...
Meanwhile, at Danville Elementary, it just snowed and school is letting out for Christmas Vacation.
(Phineas): Let's see our grades.
(Isabella): I got an A on the before-Christmas science test.
(Phineas): I got an A+.
(Baljeet): Me too!
(Buford): A D?!?! If my teacher weren't my teacher, I'd pound him!
(Paradox came in): No pounding of the teachers on my watch. And my watch can stop time.
(Phineas): Seriously, why are you always here at NSFFB? Get back to Ben 10!
(Paradox): Remember, I exist outside of time. This could be the version of me from after Ben's death of old age. Anyway, I have a mission for you. Your Phinedroids and Ferbots have returned. They plan to take the museum's time machine to go 2010 years into the past.
(Ferb): But that's when...
To be completed... I don't have much time...
