BEWARE: Foursquare Friend Request Phishing Scam

I just received the below, purporting to be a friend approval from a name i din't recognize.  It's a phising scam, hoping you all try not to open.  Not sure if the sender knew my foursquare account was attched to a specific email address, but they had me going, for sure.  If anyone wants the full headers, I will happily share.
