I like to mess with scammers. Had one guy send me a check. Got a text a few days later saying his dumb secretary sent too much and could I return the extra amount. Told him I thought that was the agreed amount. A few text back and forth and he soon realizes I'm "F"in with him and then the insults begin. They usually stop even returning my text. I turn it into a sport. One guy I just kept sending text after text after text after text clogging his phone up. Maybe like 200 text total. My wife says I have a problem
