Sometimes, insulting them can lead to them realizing the error of their ways, making a change and improving their lives. Well... maybe not. But at least it can amuse all the rest of us. And isn't that what we're all here for? Take a gander at these comebacks, and be amused with how clever some folks can be when dealing with dummies.
