Good Comebacks

Your mouth is getting too big for your muzzle.

Why don't you go to the library and brush up on your ignorance?

Believe me, I don't want to make a monkey out of you. Why should I take all the credit?

There are several people in this world that I find obnoxious and you are all of them.

You should toss out more of your funny remarks; that's all they're good for.

Have you considered suing your brains for non-support?

I don't know what makes you so stupid, but it really works!

If ignorance is bliss, you must be the happiest person alive.

I'm busy now. Can I ignore you some other time?

I'd like to help you out. Which way did you come in?

I'd like to see things from your point of view but I can't seem to get my head that far up my ass.
