Tech Support?

TECH SUPPORT: Hello, Tech Support?
CALLER: I’ve been having problems with my computer.
TECH SUPPORT: (Well, duh!) What problems do you have, sir?
CALLER: I think it may be frozen.
TECH SUPPORT: What’s happening?
CALLER: The keyboard doesn’t do anything, and the mouse isn’t
making any responses.
TECH SUPPORT: (Could he GET anymore stupid?) That is not a big
problem, sir. Just turn the computer off, and then on again.
CALLER: What do you mean, “on again”?
TECH SUPPORT: (Uh-oh.) Um, sir?
TECH SUPPORT: (God!) The screen isn’t black now, by any chance,
is it, sir?
