The best one I had was a scammer impersonating a US Marshal claiming I didn't show for federal jury duty in Ocala so the judge issued a bench warrant that he was going to execute, unless I met him in Ocala in 3 hours with $4,000 in "vouchers". If I didn't show he was going to have local law enforcement arrest me and I should have my lawyer at the house waiting for them. Took about 30 seconds to figure this out, but.....
"voucher" is the African term for bank check
I didn't think a federal fine could be paid directly to an individual marshal
And why would a federal agent charged with executing a warrant pass it off on "local law enforcement?
So I invited him to come and arrest me himself, and I would have my lawyer waiting for him---from the law firm of Smith, Wesson, Colt, Remington and Glock. I also suggested that impersonating a federal agent is likely a felony. Much to my surprise



, he didn't show up.
Since I dumped my landline, I have not received any scam calls
