The Question Was...

What is an Interrobang?

For a short time in 1967, the American Typers Association invented a new punctuation mark that was a combination of the question mark and an exclamation point called an "interrobang." It was intended to be used to express incredulity or disbelief. It never caught on with the general public, and it faded away.

I've been typing for many, many, many, ma...well, you get the idea...years and I never heard of an interrobang.
