I used to get calls from people saying that they can take my $1000 and turn it into $10,000 within a week.
I then ask them two questions....
a) If they know how to turn $1000 into $10,000 in a week, then why the hell are they still working and bugging me on my phone?
b) Since this is such a sure thing, then how about they LEND me the $1000 and I'll give them $2000 when I get the $10,000?
