Presupposution wrapped in a joke --- I guess the presupposition here was that WC was not doing his job, i.e., he was as good as dead.

However, as Bi alerted in one of her comments, the best way to test presuppositions to see if they would hold under negation. In this case not sure what would be the best way to phrase the negation:

a) "None of this would have happened if WC had been dead"

or

b) "These things would have happen if WC had been alive".

In both scenarios the premise that WC is not doing good job stands true so I guess this is indeed an example of presupposition (wrapped in a joke).

Would anyone else like to propose a different negation that would prove the presupposition wrong?
