Step 1: The fish, minding their own business in the peaceful pond, take a deep breath of oxygen-rich water. Step 2: Suddenly, a splashing noise jolts them out of their peaceful state. Step 3: They notice an overweight, nude man has waddled into the water. Step 4: Unbeknownst to them, the man lets out a resounding fart as he submerges his backside. Step 5: The fart bubbles rise to the surface, causing a commotion in the water. Step 6: The fish, unaware of what just happened but feeling the disturbance in the water, take another breath of oxygen-rich water. Step 7: Little do they know, they are now taking in the man's flatulence. Step 8: As the man continues to move around in the water, letting out more farts, the fish struggle to stay afloat in the toxic gas. Step 9: They start to feel light-headed and swim erratically as they try to escape the gas-filled water. Step 10: Finally, the man climbs out of the pond, satisfied with his swim, not realizing the havoc he has wreaked on the poor fish.
