Anyone who has ever worked in Tech Support has some real beauts to tell, I'm sure.

My best one...a client called and the receptionist processed the call normally, and put the client into a queue for help. The client didn't object and waited for about 5 minutes before I picked up the line.

Client: My PC is smoking. What should I do?

Me (astonished) : Unplug it. NOW.

Client: But won't I lose all my work?

Me : UNPLUG IT! NOW!

Client: I'm pressing 'save' but it isn't doing anything? What should I do?

Me (pounding head on desk): UNPLUG IT.
