Everyone at the festival thought the street magician was a wacko, but his tricks made them laugh.

My neighbor's wacko inventions always make the whole neighborhood laugh.

The neighborhood watch organized a meeting to address the growing number of wackos trespassing on private property.

The old radio show attracted a crowd of wackoes who loved its bizarre humor.

When the discussion turned to pop legends, someone jokingly called him Wacko Jacko to get a laugh.

Everyone laughed when the prank triggered the wackometer to spike.

Technicians deployed three wackometers across the facility to monitor sudden bursts of odd readings.
