As a huge Sr. Wooly fan, Profe Finaldi could not have been happier to get to be part of the making of one of his videos, Los Quehaceres. You can spot her briefly in the scene of the student busting into the teacher's lounge.
Also, as compensation, she received an official "Billy la Bufanda," which she is proudly wearing for in her photo with Sr. Wooly!
You must be a member to see the whole video, but you can watch a preview at the following link:
