One-armed, no-legged teenager Nick Santonastasso loves the Walking Dead. He's also made a name for himself on the internet pulling zombie pranks on unsuspecting victims. So it made sense for Walking Dead producers to fly him to Tokyo—where the cast and crew was gathered for a press junket—so he could pull an excellent prank on Norman Reedus, aka Daryl Dixon on the show.
With the help of the show's award-winning makeup team and star Andrew Lincoln, he pulls it off. Even better: the stunt was part of an on-going campaign to get Santonastasso a role on the show.
