When you see it

NO.

NO NO NO NO NO

YES

So if Doofenshmirtz is Phineas's dad, I'm guessing that includes Candace as well. So that would make Vanessa their half sister.
Interesting.

TO EVERYONE SAYING NO,
YES

Except then Vanessa would have had to be born after Phineas.

STOP
THIS IS
THIS IS JUST TOO MUCH FOR ME

Actually, the creators have said that Doofenshmirtz is not Phineas' dad.

You're comparing a chin to a nose... I mean, general face shape aside, I don't think that's exactly compelling

Guys Candace and Vanessa are the same age but doofy met Charlene after he split with Linda so he can't be Phineas's father if anything he'd be more likely to be Candace's father

I'm kinda glad Doof legacy will live on. He's amazing

AHHH

Christmas is coming

That's explain his level of creativity
