Calvin starts opening a can. He hears rumbling, realizes what's about to happen, and covers his eyes. Hobbes comes slamming into him. Calvin angrily picks up a chunk and shows Hobbes he was opening a can of pineapple, not tuna. Hobbes tells him all cans sound the same.

Calvin looks jittery as he walks along. He says the problem having a tiger for a friend is that he appears out of nowhere, coming right at you at 90 miles an hour. He looks around, startled. Calvin wipes his brow. He thought he had heard Hobbes. His heart is still pounding. He sees Hobbes on the floor. Mom tells him he hasn't been looking well. She suggests he should go to bed earlier.
