Calvin has a couple sandwiches that he's made, but he thinks Mom got suspicious. He tells Hobbes they'd better go. Hobbes is trying to decide whether to bring a yo-yo or bubbles. Calvin hurries him up saying they'll be lucky to get out of there with their lives. Calvin says Mom is bound to look out the window any minute and see the car. As they dash out the back door, Calvin asks where's a freight train when you really need one.
