Personally...I like answering the phone...Dr. Terror's State Institution, please hold while I transfer your call...punch a couple of number's then lay down the phone. Yeah, I know, its easier to block the call, just ain't as much fun.

Telemarketer's... I let them tell me all they can do for me...then I say:
Thank you soooo much...I have been looking for a really good finance company...I want to finance a house, two trucks, and boat. Well I am so glad you can help me cause the banks have turned me down along with five other companies. Oh...because, I filed bankruptcy three times and I have four felonies...hello, hello...heeelllloooo. Yeah, they don't call back.
I deal with my local bank, don't need a long distance company banker.

However, it might not be quite so humorous the way our economy is right now...more people might just be in that bankruptcy court.
