Hogwarts’s motto is really good advice. Follow it. You are crunchy and taste good with ketchup.

To help you remember, wear the Harry Potter Hogwarts Crest Thermal Shirt and Pant set. The Hogwarts crest, motto, and its symbols of the four Hogwarts houses are emblazoned on the front. The school name is printed down the left pant leg, and both the shirt and pants have ribbed cuffs. Let that crest remind you: no. Tickling. Dragons. Got it?
