Zygon (They Shall Not Pass)

A Zygon was one of the cast members of Doctor Who. On their way to work, they once forgot their pass, which officially prevented them from entering the BBC Television Centre. On the basis of this strict application of policy, the security guard indeed refused them entry, with the guard insisting that anyone could make such a claim. What the guard was, for some reason, failing to take into account was that the cast member was a big red rubbery alien covered in suckers who towered over him like a giant.
