Doofenshmirtz and the Puppet

When the evil version of Dr. Doofenshmirtz decides to send the main characters (including his less evil counterpart) to their doom, regular Doofenshmirtz objects against being sent to his doom, only for his evil alternate-self to use his sock puppet to reiterate his decision. This leads to regular Doof using this trope.
