Work on smartest, meanest comebacks and deliver them with the sweetest smile in as public setting as possible. You will kill two birds with one stone - embarrass the heck of the clowns and build quite the reputation. I am known for my abrasive tongue but someone chose to ignore the reputation. The zinger was "That's how I am twice your age and half your size". Ouch.

Or build something along the lines of "reducing my carbon a$$-print" into a comeback.

Good luck
