There was a US presidential election when I was in 2nd Grade, my teacher showed the class what the president says as he is sworn in: "I do solemnly swear that I will faithfully execute the President of the United States etc."
I used to believe for about a year following that day that the incoming President *executes* the President who's leaving. My parents laughed so hard -- apparently, they thought it was fitting for the old President to be executed!
