The Mad Doctor/Fridge

Fridge Horror
Note that the chicken is somewhat alarmed, though not entirely overwhelmed, at seeing someone in a mask strap a puppy to a chair. As soon as The Mad Doctor takes off the mask to reveal who he is, the chicken breaks down in TEARS. Apparently, the very presence of The Mad Doctor is much more overwhelming to the chicken than the presence of someone who would merely strap a puppy to a chair, implying that the chicken is well aware that The Mad Doctor has done far worse things before.
