This all closely relates with what you do with the guy from "Microsoft support" who wants to help you get the bugs out of your computer.
I've had a couple of these, the last one I spoke to said he "vas from Vindows", and that I had a problem with my computer.
I explained that if he was kosher, he would be from Microsoft, he kept correcting me saying he "vas from Vindows".
I kept telling him Microsoft and he hung up.
Bill Gates really needs to sort out his help centre, tut tut tut, how dare they hang up on MEEE!!!!!

PS Probably didn't understand what the meaning of kosher is in this context.
