6-panel Loading Artist comic. 1: A sad man sighs while fishing off a pier. A fish watches from the water. 2: The fish feels sympathy: “Aww, he looks so sad…” 3: It swims the hook over to a friend, suggesting, “Maybe we could give him something?” 4: The friend snaps, “Are you nuts? HE’S TRYING TO EAT US!” 5: The friend swims off, grumbling, “You’re such an idiot…” 6: The man happily reels in a fish — it’s the angry one, hook stuck in its tail.
So that's how snag catches happen
