Grendle the puppet reviews “YES! 50 Scientifically Proven Ways To Be Persuasive” by Robert Cialdini.

The episode of “Atop The Fourth Wall” that Grendle is talking about is the Mr T #2 comic book review

Altogether a fun and informative read. Do me and Grendle a favor and leave a comment on the Youtube page for this video (http://youtu.be/4bAXImHkJRI), because puppets love comments!
