Pig Ears

A delicacy to dogs everywhere.  They smell horrible.  Can anyone who was in class explain the funny by using the title with today's lesson?  If you missed class, plan to take the AP exam, or are just interested in learning more (weirdly, there are some of you out there), go to the Moodle and check out the newest "Forum" added - NOTE:  You DO NOT have to enter anything in the Forum - I simply created it for future use.  If you just want to skip that, you can see the linked site here.  Watch, read, and learn.  I spent a few minutes in the copy room today...making copies.  Hint Hint.  Used the staple function too.  Hint Hint.  Freak out if you must...Maybe play the link below...
