Reminds me of something my mom did a few weeks ago. She got a scam call from some guy saying he was with Microsoft and he detected a virus on her computer. (First clue it was a scam? They have an iMac. Why would Microsoft be calling?)
My mom started playing dumb and saying, “You mean my Commodore has a virus?”
“What?”
“Yes! I have a Commodore 64!”
“Uh..Do you have Windows?”
“Well, of course! I can look through them and see the birds outside! My cats LOVE my windows...But I don’t let them up by my computer after someone told me that computers have mice.”
“Uhm...Ma’am...Is there someone else there?”
“Nope! Just me, my 12 cats, and my 4 dogs!”
The guy hung up on her at that point. :)
