[Jorodryn]

[hexnut]

homonymnologically speaking; sow-smart

[LeoChopper]

I haven't heard the expression sow-smart before, so it's hard to be sure, but I would guess the opposite is pig-ignorant.

[Steave]

People eat pigs but people don't eat people and the opposite of ignorant is educated so the opposite of pig-ignorant must be the combination of people and education therefore: University.

[Funky Honky]

University is a place you go to make more money in the long run. The opposite or University is Vegas.

[Zillatain]

Vegas sounds similar to vegan, so the opposite of Vegas is carnivore.

[Thom Solo]

Carnivores consume meat, so the opposite of carnivores are seeds, which produce plants.

[Funky Honky]

::GAWK!::

Plants have generally predictable systems. The opposite of plants is Calvinball.

Yeah, this looks like a decent spot to get this bad boy under control.

[Zillatain]

Calvinball is a game that has no rules, so the opposite of Calvinball is bureaucracy.

[Galaxy Hunter]

Bureaucracies are generally cluttered with various things too close together, so the opposite of a bureaucracy is outer space.

[Solara Hanover]

Outer space is full of stars, so the opposite of outer space is reality television

[Zillatain]

The reality television genre tends to be about some type of stupid competition between people to entertain the watching masses, so the opposite is a Stephen Hawking.

Stephen Hawking is a hyper-intelligent cripple, so the opposite of Stephen Hawking is the Situation.
