Your best comebacks? What are they? Here's mine:
Riding back to CA through Bend, OR - stopped at Starbucks and parked next to a couple of Harley guys - 1 of them was on a silver/black '03 Anniversary edition.
He looks over my Aero (the original one!) and says - "What is that?", so I tell him, it's a Honda Aero.
Him: When are you going to get a real bike?
Me: When is your bike going to get a real rider?
Then he asked about my paint - How did I decide on the colors (red/cream)?
Me: Well, that was pretty easy - I didn't like black and silver!
