Going in Circles
Me: “Want any souveniors from home?”
She: “Bring me back a crop circle.”
Me: “The ones made in soybean fields aren’t as impressive as the corn ones. They’re made by shorter aliens.”
She: “You can judge the size of the invading alien horde by the height of the crop they deface?”
Me: “Yep. Personally, I wouldn’t get worried about it until they start knocking over sunflowers.”
