Dennis the Menace #89

Dennis the Menace takes his usual delight in turning a simple door-to-door sales pitch into chaos, much to the frustration of a vacuum cleaner salesman trying to demonstrate his wares. As the man’s patience wears thin, Dennis’s antics reach a peak—so the salesman hangs a sign warning off future agents.

Melvin and his friend give a rusty lawn mower a once-over, only to send it roaring to life with a vengeance. Before they know it, Melvin's dad is caught in the chaos, riding the runaway machine down the street in a wild, unintended sprint.

In "Blackout!", Dennis the Menace turns a simple power outage into a week-long prank by deliberately tripping the circuit breaker when the lights come back on—leaving his parents in the dark and his mischief just getting started. The story captures the classic chaos of a mischievous kid finding joy in the unexpected, all in the timeless humor of a 1967 comic.
