I used to annoy one of my old college roommates with a sock puppet named Dr. Spencer that was specially constructed to annoy said roommate.
The rules of puppetry, as I understand them from my time with Dr. Spencer, are as follows:
1.) Blame all of your shortcomings on the puppet.
2.) Speak in the most annoying falsetto you can manage.
3.) Act shocked when the puppets suggests (or outright says) horrible things about your roommate.
