Called with a typical credit card interest rate reduction scam. I always like to mess with these guys, so I pretended to be interested but asked them which one of my credit cards they were calling about (knowing that they have no idea which ones I have). The called said they were affiliated with all the major banks, and asked for details of one of my cards. I told him that I just didn't feel comfortable giving that out and he said "OK, Do me a favor". I said "Maybe, what is it?". His exact reply was "[***], and tell me the flavor", and then he hung up on me.
