you know the sort, someone who can write a reply that is both witty and stinging without actually being offensive in any way shape or form

the story is a little something like this:

got a call from someone i the office who wanted to know stuff
i gave her the answer
she asked me the same question again
i gave her the same answer
this went on for about 5 minites
then i put the phone down on the side of the table and walked away
she then called me 7 times
and sent me an email saying "can you call me back so we can finish the conversation"

so i need to send soemthing back that basicly says "get bent", but without saying "get bent" in any portion of the email

thank you kinds sirs (and ladies if you can get in a good reply)

it's got to be short and to the point as well, just that one killer line that will tell her what's what
