Weirdest spam E-mail ever.

So, I received this e-mail the other day:

Dear customer!

The money transfer you have sent on the 2nd of March was not collected by the recipient.
Due to the Western Union agreement the transfers which are not received in 15 days are to be returned to sender.
To collect money you need to print the invoice attached to this email and visit the nearest Western Union branch.

Thank you!

Last time I checked, I've never used Western Union before, and this did not come with any "invoice" to print, or any other attachment. The only thing I can think of is that it's one of those e-mails that are supposed to infect Outlook type e-mails (and since I use POP type e-mails, no worries).

Just felt like posting my confusion on this thing.
