Simpsons Illustrated #24

"Mr. Burns tricks the 'unsinkable' Homer Simpson into swimming the toxic waste-filled Springfield Channel as a publicity stunt. But what's a dip in the water without a little childhood trauma and a killer whale out to settle an old score. Then, Lisa rises to the challenge when she attempts to solve the mystery of a missing ice cream truck, and Bart enters into a summer school showdown with Kearney."
