One of my favs was the mother of the wife of a friend.
She: "So you are a programmer?"
He: "Yes"
She: "I have a small problem, could you help me ?"
He: "Ofc, what is the problem"
She: "Well my washing machine is not working anymore."
I just love this one ;D .... since there is an digital display on her washing machine and he's a programmer he should be able to fix it :D ....
