As an example, my sister's ex-boyfriend (they'd broken up before this) was a pathological liar who bulled his way into a job at a wildlife park on the basis of watching a few similar shows on TV. In the first (and last) month of his employment there he lost an arm (at the shoulder) to a large croc in front of the tourists when he went in to the enclosure to feed her. He didn't know how to approach them and the Steve-Irwin-Types made it look much easier than it really is.
