As has already been mentioned several times in all the "failed audit" meta questions mods have no say in what questions go into audits.
Technically though, that is an actual valid workable answer to the question. That there are other and better answers is irrelevant.
It sounds ludicrous, and it probably was meant as a joke but it is a solution that would probably work. That makes it an actual answer.
Mods, while having a greater say in what happens on the site, are slightly constrained in how they can act. Unanimously running rampage across the site deleting anything that we find is considered a "no-no". We try, wherever possible, to act with the community consensus of what is acceptable on our site.
Just because someone doesn't like an answer or thinks an answer it "too silly" or is "missing the point" does not make that answer any less valid than any of the other answers and mods have to keep that in mind when dealing with flags.
If you want that answer gone from the site then I would recommend asking a meta-question specifically asking whether we should allow these types of answers. Generally though (and I know this is regarding questions) we don't hate fun.
