The story of Upside-Down Calculator

Math class came to a halt the day someone discovered the calculator could talk. Type the right numbers, turn it upside down, and the screen said hello. Kids built whole conversations out of words like shoe, goose and bilge. The teacher pretended not to be impressed but definitely tried it.

Fun fact

The longest word anyone in our school ever spelled was eleven letters long, and nobody could remember what it was.
