I usually just hang up immediately after I hear an Indian accent: “This is Vijay from Bombay and your computer is werrry, werrry sick!”
However on a few occasions, I have been known to do the following:
“Oh, I’m so glad you called. My computer is making this really weird noise. Wanna hear?”
Then I blow several blasts on a police whistle into the receiver, loud as I can manage.
Oh my dear Indian pal. Even sicker is the game they’ve put you up to.
(if i got a call like that, which clearly was a hoax — but I never got one yet)
