If you watch the scene where Bartleby and Loki go to the Moobie's Corp to kill everyone, If you watch Loki right after the guy realize theyre sitting there, Loki is carving himself a voo-doo doll out of a onion. If you look closely, as he is carving, he accidentally cuts the dolls head off, smiles as he realizes he messed the scene up, but still acts as normal, continuing the scene. A couple clips later, look at the doll, it magically has a head again!
