Mr. and Mrs. Doofenshmirtz

Mr. and Mrs. Doofenshmirtz are Heinz and Roger Doofenshmirtz's parents and two minor antagonists in the Disney cartoon series, Phineas and Ferb

Why They Suck

 * 1) Mr. Doofenshmirtz turned his son Heinz into a lawn gnome and forced him to stay guard.
 * 2) They completely treat Heinz like dirt, and spoil their other son Roger, leading Heinz to become the villain he is today, and even then he's more likable than those two.
 * 3) Mrs. Doofenshmirtz neglected Heinz because of dull ability of playing kickball, but hey, he's great with his hands, but does his mother care? NO!
 * 4) Mrs. Doofenshmirtz forced Heinz to wear dresses, and embarrass himself in front of his manly classmates.
 * 5) Neither of them showed up for Heinz's birth, which raises a lot of questions once you think about it...
 * 6) Forcing your son to throw your own birthday party? How abusive can you get?
 * 7) They're two of the only bad characters on an otherwise good show besides Suzy Johnson.
 * 8) While Candace is often the antagonist, she's neither evil nor truly spiteful - only impulsive and a bit high-strung, and has shown on occasion that she genuinely cares for her brothers.
 * 9) Even the main antagonist Doofenshmirtz is quite Affably Evil, loves his daughter dearly, and is an absurdly Friendly Enemy to Perry. His attempts to take over the ENTIRE! TRI-STATE! AREA! come across as more pretending to be evil to get attention than the evil acts of a power-mad lunatic.
 * 10) Meanwhile, Doofenshmirtz's parents don't have any redeeming qualities and only exist for Doof to have a reason to raise to villiany.
 * 11) While their son Heinz is an evil genius, they look like they came from the Middle Ages which is out of place.

Reception
Mr. and Mrs. Doofenshmirtz are considered to be two of the series' worst characters by fans alongside Suzy Johnson.
