Phineas and Ferb, Season 1

Dr. Doofenshmirtz:
And now Perry the Platypus, you will finally understand my pain. Back in Gimmelschtump in the days of my youth, the Doofenshmirtzes were a proud family. But those were lean times for my father, and our beloved lawn gnome was repossessed. Who would protect our ancient garden from witches, spells, and wood trolls? From a tender age, my father decided that it will be me. While the other children played kick the schumptel and ate doonkelberries, I would stand for hours. All through the cold night, as the spitzenhounds howled... My only companion was the moon. And my neighbor Kenny. So, since my lawn gnome was taken from me, I will destroy every lawn gnome in the entire Tri-State Area!
