Hilarious! You should check out Scammer Payback and Scambaitor on YouTube. These guys are great!! I love when Scambaitor takes over all the computers in the call center or takes down the entire building..LOL!
I had a scammer call me and I pretended to give her my credit card number (gave a fake number) which didn't work. Did this about 4 times and finally, in an Indian accent she said, "What type of shit you are trying to pull muthafucker!?" lol
