Ray Bradbury's captivating explanation of his Mr. Electrico character's uncanny origins

As Ray Bradbury fans know, there's a curious minor character named Mr. Electrico who turns up in his creeptastic 1962 novel Something Wicked This Way Comes. Bradbury always insisted Mr. Electrico was real but scholars never could confirm that. Then in a fantastic interview from 2010 by Sam Weller in The Paris Review, Bradbury tells the uncanny story of how he met the real Mr. Electrico:

...He was a real man. That was his real name. Circuses and carnivals were always passing through Illinois during my childhood and I was in love with their mystery. One autumn weekend in 1932, when I was twelve years old, the Dill Brothers Combined Shows came to town. One of the performers was Mr. Electrico. He sat in an electric chair. A stagehand pulled a switch and he was charged with fifty thousand volts of pure electricity. Lightning flashed in his eyes and his hair stood on end.

The next day, I had to go the funeral of one of my favorite uncles. Driving back from the graveyard with my family, I looked down the hill toward the shoreline of Lake Michigan and I saw the tents and the flags of the carnival and I said to my father, Stop the car. He said, What do you mean? And I said, I have to get out. My father was furious with me. He expected me to stay with the family to mourn, but I got out of the car anyway and I ran down the hill toward the carnival.
