Pez instructions

Gillian wanted Pez for dessert tonight. She had a brand new lamb Pez from her Easter basket. She couldn't open and asked me for help "Why do they make it so hard to open?" I said "I don't know." Then she asked "Why do they put instructions on the back?" I said "I don't know. It's so easy." She said "Yea. It's like putting a pickle in the oven." Never heard that analogy before.
