ROFLOL...you'd better be careful...even Fox news anchors seem to be having trouble distinguishing between black humor and serious opinion. They mention this morning on Fox and Friends that some conservatives equated the death of former First Dog, Buddy with the death of Vince Foster. I couldn't believe THEY'D be so stupid as to believe some of us were serious. I'd believe it of Salon, but Fox???
