Just as the set of "Harry Potter" boasted countless magical props and knickknacks, so did that of its prequel series, "Fantastic Beasts." The actors looking to snag memorabilia had plenty of options, from the period fashion pieces of 1920s New York City to the blood pact necklace of Albus Dumbledore (Jude Law) and Gellert Grindelwald (Mads Mikkelsen).

For Dan Fogler in particular, his character of Jacob Kowalski makes some tasty-looking baked goods and even gets his own wand in "Fantastic Beasts: The Secrets of Dumbledore." He also becomes immersed in the magical beast-filled world of Newt Scamander (Eddie Redmayne). Fogler joked to Collider about stealing an Erumpent puppet — a massive creature with an explosive horn. Since this wouldn't exactly fit in his car — and given production's strict rules about taking stuff from the set — Fogler secured something else in an honest manner. He told WENN, as reported by AceShowBiz, "I waited until the very end and went to Colleen Atwood, who is the costume master, and said, 'Is there anything from the costume I could take, like a piece of cloth?'"

Atwood agreed to let Fogler keep Jacob's socks, a tradition they've upheld at the end of all three "Fantastic Beasts" movies. The actor usually keeps them safely tucked away, but does wear them sparingly. He told WENN, "I only bring them out for special occasions, like premieres. The first movie I had mismatching socks, so that's a hard one to wear out."
