A group of people from the city saw on the news that a grumpy, but mostly harmless, farmer was being harassed by mean people because they don't like what they had to say. These people got together and traveled down to his farm out in the country. Having never seen a lolcow farm before, they are naturally curious.
They find Old Man Moon on a cliff overlooking the valley his farm is in. From here they can see it all, the roaming lolcows, the laughing onlookers, and the enormous walls surrounding it all. "Mr. Moon! What is this farm for?" The city folk ask, and Mr. Moon, without turning around answers, "Like to laugh at retards, niglets, and trannies. Watch 'em from here." The city folk nod their heads, they've heard of zoos before.
"Mr. Moon! Why are your walls so thick and so high?" The crowd asks. Again, without turning to them, Moon responds, "Had to build 'em. Bad people don't like it when people know they're bad people doing bad things. Kept attacking my farm. Bad year for crops." The crowd nods again, they know that bad actors don't like it when their history is known.
"Mr. Moon! With your walls so tall, and your cows safe and secure, what will you do to stop the people attacking your farm?" Moon pauses for a moment, and finally turns to face the crowd. The wind blows. His long, flowing hair billowing. His coat opened, revealing glistening six-pack abs.
"Now we build the spear, to send a message"
