The ABCs of Canada
"N is for Niagara Falls. Hear the roar of the water..."
"Why did you say 'roar'?"
"Because the water makes a loud noise."
"Is there a lion in the water?"
"No, it's just that waterfalls are very loud and the noise they make kind of sounds like a roar."
(I'm kind of disappointed, too. A lion in the water would be a much cooler explanation.)
