Me "Hey, IT Help Desk, my computer is making a funny noise."
IT Guy, "What does it sound like?"
Me, "Ummm, like a motor running really hard or something."
IT Guy, "Are you sure that sound is coming from your computer?"
Me, "Ah, yeah."
IT Guy, "Are you sure cuz I can't hear anything."

Ok, I get it. You know everything and I know nothing but shove off, you smug bastard.
