Every so often, someone comes along who is deserving of an insult. Although insulting someone is never a nice thing to do, some people need them. Some people are to be insulted because they're bad people, others are just so easy to insult that it would be a shame to miss out. And to be honest, some insults are hilarious.

The issue with insults, though, is that they are all so overused. The classic, cliché insults don't actually insult anyone anymore. Overused insults lose their punch, and that's no fun.
