Look closely at the side of Heinz' head.
Now, what is similar between these two faces?
Alright, that first picture is extremely blurry, but the point (heh, I make joke) is that as well as both their faces being triangles and they both have blue eyes, HEINZ HAD THOSE SAME FRECKLES WHEN HE WAS A KID!!!
For people who entirely deny the theory that Heinz is Phineas' father, they sure are making it easy to prove. [Mind-blown Emoticon]
(And I'm not even a supporter of that theory.)
