In the very first Calvin and Hobbes comic strip, Calvin's dad is working on the car, when Calvin walks up in a safari hat and says, "So long, Pop! I'm off to check my tiger trap! I rigged a tuna fish sandwich yesterday, so I'm sure to have a tiger by now!" His dad replies, "They like tuna fish, huh?" As Calvin walks off, he says, "Tigers will do anything for a tuna fish sandwich!" The final frame shows Hobbes, hanging by his foot from a tree, munching on a tuna fish sandwich. He says to no one in particular, "We're kind of stupid that way."

Every day we are tempted, even by traps we design ourselves. And we fall we become less than we can be. Without giving it much thought, we choose what's easiest. We seldom consider how much more is possible. We take tuna fish when we could do better. We're kind of stupid that way.
