I have a friend who I thought was sane, yet he gave over 400 K to several accounts who he thought were women interested in him, one was jennifer aniston and another was megan fox. he sent 40 K to another claiming to be salma hayek, apparently she sent him a pizza. someone told me he could get most of the money back, but he refuses to do so because he still believes. 
I remember some years back i knew a woman who thought she was writing to a
US Fighter Pilot ala..Tom Cruise type Guy, she wasn´t a good looking woman & i think there was some issues with her.
Told me she sent a large sum of money & even borrowed money of her parents
tried to explain how it is with internet scammers...but i don´t think she really listened.
Another nutter i met was a woman who met some guy online who as she told me was an
"ex Lawyer" also said first thing in the morning he was drinking.
now this woman wasn´t bad looking but also had issues. apparently this guy loved to piss on her & when i said
WTF?
she tried to make it sound OK because
"they did it in his bath"I found out later he put her on the Game & pimped her out...silly Cow
