Guys, why not have fun with them? It's their call, so, just do not answer any of their questions, ask them totally unrelated stuff, such as.. What color car do they have, start telling about your dog, the weather or whatever.
Have fun with them. Tell them you collect car hubcaps, or second hand beer bottle caps, even tell them you work for Microsoft as well. Ask them if they have met Bill, of if they have been to his house. Tell them you work for AVG, and if they are interested in a special offer..
Have fun, it's their call..
