Rebar

During a fight with a nest of vampires in 15.20 Carry On, Dean sustains a fatal injury when he is impaled on rebar.

Fans who were upset by Dean's death, and particularly that it was during a run-of-the-mill vampire hunt and not an epic heroic battle, while others pointed out Dean did die a hero saving two children from the vampires. The detractors would dubbed the rebar a "rusty nail." Some took it further, charging sarcastically that Dean had died from tetanus that he got from said rusty nail.

Others doubted the injury could kill Dean, however the rebar could've ruptured the descending part of his thoracic aorta, which runs along side the spine.

In February 2021, the rubber rebar prop that was used in the episode -- advertised as the "Barn hook of death" -- sold on eBay for $4,750.
