Don't know. It was in my inbox this morning. Maybe it's a mole trap and I'm the only one that got it.
If it's from the University of Pittsburgh and/or Carnegie-Mellon, it's legit.
My fellow alum Skins asked for it.
But if one is a mole, I suggest one don't participate.
Some primitives, especially that brassy arrogant woman primitive from Maryland ("faygoldkid" or somesuch stupid primitive screen-name), were upset about it when receiving it circa, oh, about a month ago.
