I remember when I first started with IT, I was speaking by phone with normal little customers, not big companies... these are the things I remember most which sometimes make me laugh
===========================================
Me:Sir, what operating system are you using?
Cust: Operating what?
Me: Operating System Sir, Windows, Linux, Mac?
Cust: Why you need this information?
Me: Well, Sir, it's necessary to start the troubleshooting
Cust: mmm.... let me see, actually I have 2 windows in my room
Me: I put the customer on mute and I started laughing

===========================================
===========================================
Me: Sir, please go to the control panel
Cust: Control what?
Me: Control Panel, Start -> Setting -> Control Panel
Cust: mmm, I can see Start, but not setting
Me: strange, very strange, so what do you see there, sir?
Cust: I can see Internet Explorer, Windows Update, Programs ... Settings,.. ah yea, settings, is here
(this or similar happen maaaaaaany times)
