answers to email subjects

Sometimes when I read through my spam mail I answer the subject lines out loud before deleting them. Some examples:

Want a new or used car?
no thanks I have one

Someone wants to date you
yeah I know, but I'm married already

webcam? where did you go?
I didn't go anywhere and quit calling me webcam.

Third attempt- Your check is waiting
Yeah well it's gonna have to be bored.

RE; this could be what you have been waiting for
but I doubt it

Mortgage rates are falling
watch out!
