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 so hard

 * 1) Mr. Doofenshmirtz turned his son Heinz in lawn gnome and forced 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, how is that even possible?
 * 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.
 * 8) Phineas and Ferb are short on flaws, as are many of their friends.
 * 9) 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.
 * 10) Buford is a card-carrying bully, but is a Jerk with a Heart of Gold who is clearly friends with his "victims".
 * 11) 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.
 * 12) Suzy Johnson appeared to be a straight Jerkass in her first appearance, but later episodes revealed that she's a sweet girl whenever Jeremy's not around.
 * 13) So, the only really unpleasant recurring characters are Doofenshmitz's parents in his tales of his Hilariously Abusive Childhood.
