So, I haven't received any of these before: "We happily announce to you the draw of the Euro - Afro Asian Sweepstake Lottery International programs held on the 1st of April 2004 in Dakar Senegal. Your e-mail address attached to ticket number: 56475600545 188 with Serial number 5388/02 drew the lucky numbers: 31-6-26-13-35-7, which subsequently won you the lottery in the 2nd category.

Right. As if.
