 is the song sung by Dr. Doofenshmirtz during The Dad-inator.

Lyrics
''Dr. Doofenshmirtz: Hello. Dr. Heinz Doofenshmirtz here. Your child asked me to tell you something, and I decided to do it in song form 'cause...you know, that's how I roll.''

Though your child is not exactly evil Not wicked, vicious, sinister or mean (it's a pity, really) Still, I certainly can't complain Your progeny showed some brains By sending me to appear upon your computer screen

I hate to say it, but your child really likes you Though I hesitate to sound cliché It's time to literally bang a gong As I belt out this song Wishing you an incredibly evil Father's Day!

Dr. Doofenshmirtz: Oh, that was much louder than I thought it would...anyone got a softer mallet? (Perry growls)
