Comebacks

So, a thought crossed your mind? Must have been a long and lonely journey.

Pardon me, but you've obviously mistaken me for someone who gives a damn.

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

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

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

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

Have you considered suing your brains for non-support?

Don't you need a license to be that ugly?

I see the wheel is spinning, but the hamster looks dead.

If you had another brain, it would be lonely.
