Dubious

Sometimes life has a delicious sense of irony. I got one of those implausible spam emails today promising me a fortune if I give someone my bank information. A nice gentleman named Eric Harford from South Africa promised me the deal of a lifetime!

I am Eric Harford,and I work in the international operation department in a Local Bank here in South Africa. On a routine inspection, I discovered a dormant domiciliary account with a BAL Of 36,000,000 (Thirty Six Million USD) on further discreet investigation I also discovered that the account holder has long since passed away(dead)leaving no beneficiary to the account.

I will provide you with the necessary information all the legal documents needed in other to claim this money, But only what you will be required to do is to open an account where this can be transferred urgently even an empty a\c,is still ok!. So if you are interested capable, then send me your private Telephone Number immediately so that i can call you for more details. Send to me any account number you would like us to use to make this transfer.

The email is formatted fairly well, and the spelling is mostly correct, but the atrocious grammar belies its shady intentions. I guess the subject of the email is a dead giveaway, too. But just in case I wasn't sure about it, my own email box gave me a subtle hint as to the nature of the message. Look what email appeared right below Eric Harford's offer:

Yes, that's right, the word of the day is dubious.
