If you work with someone like this, you have my condolences.
One of our servers crashed. I was watching our new system administrator trying to restore it. He inserted a CD and needed to type a path name to a directory named "i386."
He started to type it and paused, asking me, "Where's the key for that line thing?"
I asked what he was talking about, and he said, "You know, that one that looks like an upside-down exclamation mark."
I replied, "You mean the letter "i"?"
And he said, "Yeah, that's it!"
