Ya know, this Porsche Bob/Jack Olsen thing is really bizarre. The more I think about it, the more I am puzzled, and the possibilities are endless.
Both are pretty good writers . . . which leads me to wonder: Jack, did you create Porsche Bob in order to get control of the rampant man crush phenomena of which you appear to be the object? If you did, that is pretty clever indeed.

You might even be able to write a script about it.
On the other hand, you might inadvertently increase your stature by maintaining class, grace and dignity in the way you respond to Porsche Bob, which would cause the strategy to backfire.
In any event, it is pretty entertaining. You don't see this type of thing at the other boards I have visited. Cheers!
