virus phone call scam: question/wacky replies

[Tom Sparks]

'We have been getting phone calls say "your computer has a problem..."
Most time I just hand up. But I've been think of give these caller a 10 question or some wacky replies

 1 What Operating System I am I using?
 2 What's my local/network IP address?
 3 What's my router's IP address?
 4 What's my Internet IP address?

 * Must be my Atari 2600, How did that get on the Internet?
 * let me drag out my PDP-10.... do you want to debug that for me?
 * Where my ARPANET IMP?
'
I am wondering what question or wacky replies would you come up with?
