Don't "moolest" a puppy.

Parodied in the Smosh video "WORST ID PHOTO EVER!". A Running Gag is people calling Anthony a "puppy moolester", claiming that by petting a puppy without asking its permission first, that means he's "moolesting" it. One of the people calling him a "puppy moolester" is an ornery DMV lady who insists that he has to retake his driver's exam if he wants to change the picture on his ID, and she insists that he has to do it without "moolesting" a puppy she brought with her. He doesn't even make it out of the parking space before she fails him for petting it.
