guys i have a theory

i knew his mama cheated

But that's just a theory a film theory

real

It makes perfect sense

Fr

They both know how to create advanced machinery

Whoag

that theory's existed for ages but Dan Povenmire disproved it

Shut up nerd you ruined the joke

i ain't a nerd i'm saying the creator of the show has gone on record and given evidence that there is no logical headcanon where Doof could be Phineas's dad

still ruins the joke

Bruh he isn’t ruining the joke he’s just supporting it wdym

he is ruining the joke but ok

-both extremely smart
-same haircut
-kinda the same head shape
yup their def related

exactly because of the head shape
doophensmirtz and ferb both have triangle heads doof's is just vertical while ferb's is horizontal

saem

Makes sense
