Unannounced and via overnight courier, you receive a check for $500,000 drawn on the account of a Canadian corporation together with a cover letter stating you have won a major prize and need to deposit the check with your bank right away. Your bank might even tell you that it appears to be drawn on a valid account. Later that day, you receive a call informing you that a mistake has been made, that taxes were not deducted from the check, and that a stop payment order will have to be placed if you do not wire $20,000 to $30,000 immediately. Days after you wire the money out of the country, your local bank informs you the large check was dishonored because it was counterfeit.
