give it back to them. Not sure about how they mean it but in most cases it's just in fun and you can dish it back to them and everyone have a laugh. There is Ride a harley, ride the best, ride a mile and walk the rest. Or Did you know that 99 out of 100 Harleys ever built are still on the road today? The other one made it home. Just give em stuff like that. My HD riding friends and I give back and forth all the time and it's always a laugh in good humor.

I learned all I need to know about life by killing smart people and eating their brains.
